I've been taking biaxin for a viral infection for about 4 days. At first I had the metallic taste in my mouth (my doctor told me this was common), but for the past couple of days I've been feeling detached, somewhat depressed, and have had a low sex drive as a result of the detachment. Should I switch to a different antibiotic or stick it out for the last 6 days? And if I go the full 10 days, how long will it take for my mood to go back to normal?
