Biaxin and incredibly

I have been taking Biaxin for 9 days now - 2 pills a day at the same time. I have been taking it at night - and have had the worst experience with the medicine. Along with everyone else, the metallic taste is awful... I taste it really bad in the mornings, then it seems to go away as the day progresses. I am incredibly emotional, depressed, lots of anxiety and panic... All of which started when I took the first couple doses of the medicine. I was prescribed Biaxin due to a severe upper respiratory infection and a sinus infection. Both of which seem to be improving - I still have a cough with some wheezing and chest pains. Also, my lymph nodes are still swollen and very tender. They hurt to the touch. I don't know if it's the medicine or if there is something more serious going on. I have 2 days left on Biaxin and will NOT be taking them. I will never ever ever take Biaxin again..

After two days of taking Biaxin XL, I feel much better physically; the metallic taste in my mouth is tolerable. A possible side effect that concerns me is I've since been experiencing sleeplessness, increased energy and an incredibly good mood (I like the good mood and energy) but is it facilitating a move into a manic phase? (similar to what Prednisone has been known to do) I'm otherwise a healthy person with no hx of depression or any other mental illness. Anyone else experiencing this?
