bacterial infection
"Doctors need to discuss side effects of this medication IN DETAIL before letting someone go home with it. I was prescribed 7 day treatment, twice daily 500 mg tablets.  Day 1-5.. Definitely felt very tired and almost high like I was on drugs.  Somehow I continued to work everyday. Increase in urination as well as the metal taste.  Day 6-7 were the worst. I got the worst case of hives all over my entire body. Raised little red bumps. I wasn't too nauseous throughout the entire process because I made sure to eat bread or crackers before and after taking each pill. Also, my hair started falling out more than normal. The withdrawals were horrific. Felt like I had the flu, and couldn't get out of bed for a day.  It's day 9 and things are better."
