Hey Kelly -
You may want to check out a couple of places...first, the Dieting with Obstacles area may be a good fit for you, if you are on Metformin for a medical issue like PCOS...or the Dieting with Diabetes forum, if you're on Met for diabetes.
You might also join the 40-somethings chat...weekly chat and accountability for those in your age group.
Otherwise, just settle in, find a spot, and keep posting. Can't wait to get to know you better!
