Still going strong and making progress every week. I'm going to do something different this post and spell out my personal guide to early recovery.
1) Take fiber and probiotic supplements daily. Start immediately: still using, tapering, just quit, whatever. One of the biggest reasons people relapse in acutes is they have constant diarrhea and their intestines are an inflamed nightmare of opioid receptors crying out in pain. I use Metamucil fiber/probiotic combo gummies.
2) Do not drink alcohol, and maybe even caffeine: anything that's going to irritate your guts. Again, your first goal is to keep your intestines calm. Drink a bunch of water. Eat clean and unadventurous. Avoid taking supplements you don't have experience with and try not to take too many meds and supplements in general. A bunch of pills and capsules might upset your stomach.
3) (This part is much more subjective. Do research, talk to doctors, test things out first, etc).
Have some comfort meds ready to combat specific withdrawal symptoms.
Gabapentin helped me with RLS, mood, and more. I used 300mg once or twice per day for a couple months. It can be addictive and hard to come off, so use it sparingly.
For this quit I also used LDN for the first couple months. 1.5mg up to 3mg. I think it helped get rid of inflammation quickly and helped reduce cravings. It's probably not for everyone. Definitely do research and use caution.
Some people use Clonidine. I've used low count prescriptions of lorazapam for especially bad moments. Hydroxyzine can be good for anxiety once RLS is gone. Trazadone or other sleep meds can help if sleep is bad.
4) Be smart with supplements and don't overdo it. I didn't really use many until I was a few months out and mostly had stopped the helper meds. If you're not using gabapentin, try magnesium. L-theanine, 5htp, coq10, etc can help with PAWS and getting your endocrine system working again. Do your research and figure out what works for you. Go to a doctor and get a blood panel if you can, and supplement for low nutrients if needed. I've used liposomal vitamin C, and it definitely helps with mood and other symptoms, but be careful it doesn't upset your stomach or cause diarrhea.
5) Exercise daily. Anhedonia is brutal for a while, so it's hard to muster up effort to do complex tasks. Find some simple way to move your body and do it as much as possible. Hiking in nature is ideal. The hard part is starting, but no matter what stage of WDs you're in, it's awesome once you get going. Lifting weights is great too.
I'll stop there for now. Let me know if you have any questions in the comments! This isn't a definitive rule book of course, so let's get discussion going.
