OK I have a weird side effect to ask about. After a few hours of taking this, I noticed a rush of heat starting from my butt and going down my legs. I thought, "What the h#ll?" I have read on here about the hot flashes and I'm going to attribute that to this drug. Here's the thing that I haven't yet read and was wondering if it has effected anyone else like this.. This sounds funny but is not. My "boodyhole" goes like in and out at will sometimes. You know, and I hate to be graffic, but when you use the restroom and having a bowel movement and you finish; everything kind of goes back in. It's that sensation that of going "in and out". Anyone? Anyone?
