Hi, I've been lurking on the board for about a year, but this is my first post. I just wanted to say that WW is not for everyone. (Regardless of what others may tell you!)
I was on WW for an entire year. 12 whole months! I followed it exactly, just like you are doing and lost 8 lbs. 8 lbs in an entire year!
I gained a lot at first, about .25lb a week. It took the entire year to lose the 8 lbs. I think that it is not the best with IR/PCOS.
For example, you can eat a lot of 100cal packs and stay within your 27pts. IMHO, there isn't enough support there for IR. Go talk to a good nutritionist that has experience with IR/PCOS. Good Luck!
