I have been a Soulcysters.net member for 10 years, and there is a lot of good/excellent/offbeat advice there. I have to say, after 12 years on Metformin, and having done a few Clomid cycles, it never worked out for me.
Then again, I have an EXTREME CASE of PCOS. For example, I had a 70lb ovarian tumor removed this summer & haven't had a af since 1998.
Metformin works for only a handful of people I know. Clomid, the same. Vitex has been more successful from the experiences I have been privy to.
Also, don't quit the Metformin until 2nd trimester, I have heard/read more than a handful of cases where it helps prevent miscarriages in pcosers.
Good Luck!
