Cephalexin
"The first antibiotic I took did nothing, so my doctor put me on Cephalexin AN. Within a few hours my symptoms started to subside, probably about 5 hours later. I'm now on the second day and I feel back to normal after 11 days of what seemed like hell. It makes me feel slightly nauseated but it's worth it. Make sure your taking probiotics as antibiotics kill good and bad bacteria."
