Macrobid
"Currently on day 4/7 100mg BID. I went from feeling like my back was being ripped open and sobbing until I couldn't anymore from the pain to waking up the next day after my first dose feeling like a new person, this antibiotic is ok in my book! Mild GI issues, decreased appetite, and headaches are my only side effects. Nothing in comparison to what I was feeling before. All antibiotics aren't fun to be on, so keep that in mind before writing scary negative reviews. Hopeful that the Macrobid clears this up."
