This never happened to me before.. I got up one night and went into the bathroom to urination, and just after im done and all of a sudden I broke out in a cold sweat and felt real weak.. It lasted for a couple minutes.. It felt like I had the flue and was about to get real sick... But I didn't ( before breaking out ).. Matter of fact I feel fine! After it passed I looked in the mirror and my face was white but again.. I felt fine. And I still do? .. Has me obsessed , i ate too much before sleep and i threw up just after i felt fine and it was really bitter and smelt so bad.
