Amoxicillin can give you a bad taste as well as other side affects such as a wierd bodily smell or funny smell in your urine. you can get rid of that taste by drinking lots of fluids such as water and try to eat a piece of bread after you take it. if that doesnt work then try putting your fluid in your mouth and then the pill. if that doesnt work then call your doctor. this can be an allergy too! your stomach has a wierd way of telling you things.
