Zithromax Z-Pak and drinking water

I am taking Zpak for strep throat. I was treated with it because I am 23 and have had strep throat/ear infections very frequently lately and the other antibiotics do zip for me. I also work in child care, and wish to get my tonsils out ASAP! The first day I had eaten nothing all day, except for drinking water. (Because my doctors office sent me to the ER, they thought I had menengitis. I DID NOT!) The medication said may take with or without food... DO TAKE WITH FOOD. Even the CVS pharmacist said so after my boyfriend called and said that I had thrown up from it. Eat with it. It has made me 1) Throw up, 2) Feel Nautious, 3) Have Diarrhea, 4) Not Feel Better Yet. It's day 4 and I better feel better soon!!! Also, I was told these are not allergic reactions. If you don't need this medication, ask for SOMETHING ELSE!!
