Last Monday, I was diagnosed with a nasal infection. I was prescribed amoxicillin to take for ten days. The infection has cleared up but I still have 3 days worth of amoxicillin to take. I was told to take it until it's finished but it's making me feel so sick now. I keep feeling so nauseous. Today was the worst. I wanted to throw up so bad that I almost stayed home from work. I had to work because I had to much to do. I felt terrible all day and to top it off I have the worst case of heartburn right now. Should I just stop taking the amoxicillin?
