tonsillitis/pharyngitis
"The secret of taking any antibiotics is full-stomach.  Meaning, you should eat a full meal even you don't have an appetite.  A bowl of rice, soup, pooridge, noodles, banana, oatmeal, peanut butter sandwich with honey, or anything you can eat. Full stomach before you take the medicine (in fact any kind of medicine even vitamins) is a key to not feel all the side effects.  Also, if you feel too much side effects (nausea, vomiting, dizziness), you may be allergic to one content of the medicine you are taking.  You should check on it!  Like, I usually get Augmentin for my tonsils and ear infection but I constantly getting the same side effects when I take it then I found out I was allergic to pennicilin content."
