Clindamycin
"I was given this for a severe sinus infection and double ear infections, received my first dose at the urgent care this was yesterday, I took my dose last night and laid down to no avail could I sleep it was so weird like I was full of energy. I did get a metallic taste in my mouth but that is all. I'm still sneezing a lot and ears still hurt but will see how I am in day 3. So far it's been good I am also allergic to everything under the sun so this is the only antibiotic I can take.."
