bacterial infection
"This wasn't right for me.  Only was on it for 5 doses, so I don't know if it helped.  I puked up the fifth dose, then got dizzy, and almost passed out on the ride to the ER.  It settled down after a couple hrs,  Had no alcohol for the past 10 days.  This likely wouldn't happen to most people.  But it's got gnarly side effects if it don't agree with you."
