I once agreed to take a very popular one to, lets say "qualify for" something. During the short amount of time I was taking it for real, I did get an inexplicable sickness which took days of not taking it for it to go away.

Yes, I tried Wellbutrin. Gave me horrible vertigo. I'd be sitting down and the room would be spinning

dilaudid makes me nauseous, that's about it

Yes, Camomile tea causes any throat infection to become worse for me since I react allergic to it. Also a few Antibiotics cause allergic reactions for me. Some vitamin concentrated orange syrups cause vomiting and nausea. As far as I know that's all.

Not really, I only felt sick when I overdosed on benzos.
