sinusitis
"Did great job of treating a sinus infection, where I had pounding headaches all day for 48 hours prior to use.  By day 2, I was significantly better.  One issue is that two pills on day 1 did wipe out bacteria in the gut. I wish pharmacist gave me a heads up.  In hindsight, I would have spaced first 2 pills out by at least 12 hours.  Took one pill at 4pm and another at 8pm.  By day 2 was fine, but I did need a probiotic and immodium to get through the first night."
