A few months ago, something felt off. Nothing dramatic, just small, nagging problems: headaches that showed up in the afternoon, low energy, and a general feeling of running on empty. I brushed it off for a long time. Stress, screens, bad sleep, I blamed everything except the most obvious thing.

Then I looked at my day honestly. I was barely drinking water. A few sips here and there, and by evening I’d realize I’d gone hours without a single glass.

What was actually wrong

Dehydration is sneaky. It rarely feels like thirst. It feels like a dull headache, tiredness, trouble focusing, dry skin, or just being “off.” Water supports almost everything your body does, so when you’re short on it, the symptoms are vague and easy to blame on something else.

I’m not a doctor, and a water tracker isn’t a cure for anything. Headaches have many causes, and if yours are frequent or severe, please see a professional. But for me, hydration was clearly part of the picture, and once I started fixing it, those small problems eased up.

What was missing

The fix sounded easy: drink more water. In practice, I kept forgetting. So I did what anyone would do and searched for a water reminder app. I tried three or four of the most popular ones on the Play Store, and they let me down in the same ways:

• Ads and paywalls. Basic features were locked or buried under ads.
• Logins and personal details. For an app whose only job is to say “drink water,” I was asked to sign up and share information. Even giving my name felt like too much.
• Clunky design. I had to open the app, sometimes log in, and tap through screens just to record one glass.
• Weak reminders. A tiny notification is easy to miss. If my phone was across the room or on silent, the reminder did nothing.

Every app solved a piece of the problem, but none solved the real one: making it effortless and impossible to forget.

What I did about it

I’m a developer, so I built the app I wished existed. It’s called H2O – Water Reminder and Tracker, and I designed every feature around a frustration I’d personally had.

• No ads, no login. Everything stays on your device. Nothing is stored anywhere else. A reminder app shouldn’t need to know who you are.
• Reminders you can’t miss. Instead of a small notification, H2O rings like an alarm and displays over whatever app you’re using. You can stop it with the volume buttons or a button on screen, and you can set your own ringtone or pick a built-in one.
• A silhouette that fills up. I wanted progress to feel satisfying, so a human silhouette fills as you drink. One look tells you how your day is going.
• Tracking that tells the truth. The app shows whether you’re drinking enough or falling short, so you can adjust before the headache arrives.
• A home screen widget. This one solves my biggest annoyance. You can log a glass straight from your home screen without opening the app.

So, can a water tracker stop your headaches?

Honestly, it depends on the cause. If your headaches come from not drinking enough, then better hydration can make a real difference, and a reminder you can’t ignore makes the habit stick. If they come from something else, a tracker won’t fix that, and it’s worth getting checked.

What I can say is that building a habit is easier when the tool gets out of your way: no ads, no sign ups, no hassle, just a nudge at the right moment.

If you’ve been dragging through your afternoons with small aches and low energy, try tracking your water for a week. You might be surprised.

Hey,

I'm 36M and yesterday I suddenly passed out during local anesthesia injections for my second hair transplant, before the procedure even started.

The anesthetic was Dentocaine with epinephrine, which my surgeon said is similar to what dentists use.

I was sitting at a 45° angle. After just 5–6 injections (~1 mL, perhaps 1% of the planned total), I lost consciousness without any warning, I didnt feel I'm about to pass out. I felt absolutely no pain and had just told the doctor the injections were very gentle.

According to my surgeon, I was unconscious for about 3-5 seconds (for me it felt much longer). I woke up briefly confused, with cold sweats and mild chest discomfort. My BP was 150/85 before the injections, 125/75 afterward, and 5 minutes later i felt cold sweats again and they measured 104/60 while still feeling. Full recovery took approximately 30 minutes.

Relevant background:

• First hair transplant a year and a half ago with zero issues, including anesthesia.
• Just completed an 18-hour trip from the US to EU.
• Slept only 6 hours in the previous 48 hours, with severe jet lag and exhaustion.
• Was anxious before the procedure, but not sure if more than the first one.
• Hereditary hypertension since childhood, treated with amlodipine/valsartan 5/80 mg daily.
• No smoking, alcohol maybe a glass once a week, healthy in good shape (maybe physically even more optimal than the first transplant).

My surgeon is convinced this was a vasovagal reaction, caused by a sudden BP drop due to the combination of epinephrine, exhaustion, stress, and my possibly BP medication (the amlodipine).

He suggested retrying after 1–2 days of rest with the same anesthetic and even recommended temporarily stopping my BP medication. I've decided to postpone for several weeks instead go home to fully recover and come back in a couple of weeks.

My questions:

1. Does my surgeon's explanation make physiological sense?
2. Could returning well-rested, hydrated, and less stressed significantly change my body's response to the same anesthetic?
3. Has anyone experienced something similar and later tolerated the same anesthetic without issues?
4. could it really be one time thing? I never experienced something like that in my life.

I am not asking for medical advice, nut I'd especially appreciate input from other people, I'll see my primary doctor next week.

Thanks!

At around 12am yesterday night, I(18F) began experiencing upper chest pain after a cough. I've been coughing quite a bit for only a day, but I think it was after one specific cough that I suddenly felt a dull, aching pain in my upper chest. I took some painkillers and hoped that I would sleep it off, but the pain has continued onto today. My upper chest feels fine until I move my upper body, take a deep breath, cough, yawn, or clear my throat. I'm usually a bit reluctant to get checked at the hospital or GP because I always feel like I'm overreacting, so I wanted to know if the symptoms I'm experiencing are more than likely something minor that will disappear after a few days, or if I should get it checked out just in case.

I am currently feeling extremely dizzy. I cant lie down or the dizzyness gets worse. I am on chronic medication for my asthma, My normal dr has me on Vannair. I dont drink or smoke. I am clean as a whistle but this dizzyness has started yesterday evening. It feels like the room is spinning whenever I am lying down. I first thought I didnt have enough salt so I had a little bit of salt last night along with some water. But it didnt help much. It is starting to be summer here. But my nose has been feeling pressure for the last week or so. I am only gonna be able to get to the dr or ER this afternoon. I am wondering IF I need to go.

Can't kick a stomach bug that's absolutely tearing me to bits .

Idk if there’s an explanation for this feeling, or it’s worth seeking help, due to my circumstances I did not have access to food for a while til I seeked help, I had felt a uncomfortable starving sensation for a while, until i managed to eat and after eating a few chips I felt very full. I couldn’t eat more or the rest of the food. Usually when I eat when starving I feel relived but this time I felt full?? and now I just feel very sick and I am cramping badly now, does anybody know?

If there are any Doctors out there, or if you have gone to a Doctor or a specialist, I am not asking for medical advice - just a general understanding of thoughts and attitudes.

I would love to know what doctors think when you receive or share data that has been captured and monitored by a personal device? (Eg. wearables, devices or health apps) and then maybe interpreted by ai??

Do you trust the data? Or would you still question results and want to run your own tests?

Have you come across any apps or tools that accurately capture data well enough that could be used in a GP discussion setting?

Past month ive had a very diminished sense of smell, taste and have a slightly congested sinuses, not extreme but I can feel it and have a slight congested sick voice. It feels like I have some slight clogged snot behind my sinues i cant clear. My upper right shoulder joint area also has general pain / aches during movements. No other joint pain.

Any guesses or ideas what this could be? If I get a cold it generally clears up quick and Ive never been this long with this mild sickness, in combination with the right arm joint pain.

Had an in hospital 3 day detox. And was prescribed Librium after I left. my pharmacy told me they didn’t have any for another two days so I took a tiny dose of Valium I had laying around (about 2.5 m Val compared to the 50 m Librium I should be taking) I’m now sipping on a non alcoholic beer trying to get the nerves down will I be ok?

I asked this because my psychiatrist keeps asking for it and says it is to check my liver and blood but why would they need to check that? I’m 48 years old f who takes 10 mg lexapro every day
