I actually took a pms/menopause course this past summer. It was pretty awesome. I remember posting a bunch of info about it here in the forums but maybe I should actually write something about it. I wrote a PMS and Weight loss article a while back but can't seem to find it. I'll keep looking.
My favorite resource though for hormonal issues is womentowomen.com The docs on that site are super helpful and there's tons of free articles on all types of menopause, perimenopause, pms weight related issues.
