I have been taking Biaxin for 5 days and have experienced the worst side effects i have ever had in my life! Nausea, headache, depression, crying outbursts, metallic taste, and wanting to sleep all day are the main ones. I have never felt depressed like this in my life. A feeling of sadness has taken over my body the past 5 days and it is miserable. Can somebody tell me why?? I stopped taking it today because I have had enough, I want my life back.
