Hey if you have a sinus infection--or ever feel one coming on try using Sinu-Cleanse or Net Poti. Basically a sinus saline rinse. I was skepical at first but after 5-10 minutes after sinuses dry and water drains---boy what relief. As soon as I feel pressure or get stuffy I use this. Really great and of course drug free. Also beware--anitbiotics are a well known stomach irritant. Good Luck! MM
