Hi, I’ve been on antibiotics, Metronidazole and augmentin due to abcess from a tooth infection in my mouth. I last took these more than 12 hours ago but still feel nauseous and have noticed a sour taste in my mouth and excessive saliva. I was given tramadol on Tuesday night and had really bad side affects ( spewing 9 times throughout the day at work) in Wednesday so was advised to stop taking it. I haven’t vommitted since I stopped taking the tramadol but still feel nauseous and dizzy and a sour taste in mouth. Help please.
