I was on Metformin for the insulin resistance linked to my PCOS. before that like BG i found that a low GI diet and exercise worked best for keeping my symptoms down. Like you i could not take Dianne either, the hormone swings for me where to great as my hormone levels are extremely high.

I have been refered to a dietician to come up with a low GI eating plan that wont affect my bf as i am not taking my metformin while bf.
