Sweating seems to be a common occurrence. I have been on Atkins for 2 months and I was sweating like crazy. It's not bad now but I find the heat really drains me and I still sweat but not like I did. One of the other members referred to it as "Sticky" and didn't know what it was, it was sweat. lol. Just think how much stuff is coming out of those plugged pores!!!
