I started Metrodinazole 500 mg twice a day three days ago for a diverticulitis. Besides feeling nauseous and losing my appetite, I am feeling dizzy and at times, I can't even remember what I have done. I till have Has someone experience these "mental" symptoms? Are they likely to subside? I talked to my doctor but since I am allergic to Penicillin my options are limited and the consequence of an infection from a diverticulitis is pretty serious. Any feedback will be welcome.
