I took 1 pill on empty stomach yesterday & super nauseous all day. Ate crackers & nothing else. Couldn't tolerate it. Felt ok waking up day 2 so tried 1 pill again with apples. After 3 hours I started severe nauseous & vomiting with some diarrhea. Tried tiny bits of toast, crackers, rice, apples with no luck. Sips of water, Gatorade & 7 up but 16 hours later still battling this. Could it be virus?
