Introduction and seeking help.

After a few doctors blew me off, i finally got a good doctor and diagnosed with with PCOS. We have been trying to get pregnant since i went of fbc in April 2009. Since going off bc i hardly ever have a period and have gained weight like crazy. I dont eat meat and have cut out almost all dairy (by choice). Im meeting with a nutritionalist, working out and following a low calorie diet but still not seeing any results. On top of it all, I've been put on metformin which is making everything harder. Makes me crave sugar which i never have before. It also makes me insanely thirsty and extremely tired which makes working out very difficult. I did a month of keeping calories under 1300 which seemed like too many calories for me (5'7" 250lbs)and only lost half a pound. I think i need fewer calories but the nutritionalist says im not losing weight because im not eating enough and should increase to 1600. This really scares me. I would love any help and suggestions i can get.
