diverticulitis
"I have had a few bouts with diverticulitis close together and was prescribed Cipro and Flagyl both strong antibiotics. When trying to take both at the same time I felt very sick, and nausea. 
I went online to read more about each of these meds. Someone with experience suggested taken them an hour apart and when taking Flagyl take it in a spoon of applesauce because it leaves a bitter taste if it touches any part of the inside of your mouth.  Put it in the back of mouth w/ applesauce and swallow with lots of water. Also DO NOT Take your Cipro with milk or yoghurt it tells you on you med info on bottle and paper info. The last time the prescription for Flagyl was dbled from 250 mg to 500 mg and it made me throw it up. "
