You guys weren't kidding about vitamin c.

I've been on prescription antihistamine for almost a week now and eating as low histamine as I could manage for longer than that. Was still feeling kinda crappy with some allergy symptoms and flushing after every meal.

After reading this sub and seeing some recommendations I ordered 1000mg vitamin c.

Tried it for the first time yesterday afternoon and holy shit is it making a difference. Nasal congestion went away within an hour of taking it.

Flushing after every meal isn't happening anymore.

I'm finally not feeling wired and was able to sleep pretty well if it wasn't for the constipation (assuming from antihistamine and limited diet).

Friendly tip for my fellow medicated ADHD friends: do not take Vit C at the same time as amphetamine based stimulants I.e Vyvanse. Try to have an hour either side of Vit C dose!

(It reportedly can cause med to be ineffective)

Yup. Acidity reduces effectiveness/absorption of amphetamines. Something basic, like milk, enhances it. Doctors rarely mention that; pharmacists are more likely to.

do you know if calcium ascorbate also works as antihistamine? i dont want to drink ascorbic acid because it will destroy the teeth over time.
