Ciprofloxacin
"I was nervous to take Cipro because I had made the mistake of reading online reviews.  To people like me who get anxiety about medication: just think, people who willingly write a review online about medication probably had an extreme or unpleasant experience, but that does not make them the majority.  I'm a petite woman that was prescribed 500 mg two times a day for a week.  The first time I took the pill I felt a bit lightheaded and woke up a tad nauseous.  However, I was not on a full stomach (too nauseous to eat with my kidney infection) and I made the mistake of not drinking a full glass of water with the pill.  As long as you do those things and avoid dairy (among other things like NSAIDs, etc) you'll be fine.  Feeling much better now"
