Metronidazole
"Been on Cipro 2x & Flagyl 3x for 7 days after diverticulitis attack.  Feeling hungry but don't want to eat.  Feeling lightheaded, a little nauseous at times, no energy, no ambition.  Flagyl taste is disgusting.  No way I was going to be able to take that 3x a day for 14 days so I cover it with peanut butter and then swallow (just like the dogs)!!  Pain was pretty much gone after a couple of days but hardest part is the bland diet and no or very little calcium.   Think some extra spicy hummus brought this on.  May have to give up the hot peppers."
