I'm on Diane (well whateva the cheap brand is of that anyway). It was explained to me that going back on the pill would pull all my hormones back into line and give me the boost some of the hormones that we low and then lower others that are high! I have to say I feel the best I've felt in a long time but this is also in combination with exercise and diet. Just nice that finally after months of feeling like giving up cause nothing was working now it is finally happening. I have friends who are so against the pill and artificial hormones but I have to say its been good to me.
