Sarah & Cycla,
I'm just the opposite. Since having a baby I went hyper - Graves disease. I'm on meds, weaning off actually! I don't have any energy these days either but I put on 12 pounds this winter and I can not get it off. It seems the more I watch my calories, cut out fat and junk, I gain weight. I don't get it. I see a new endo April 17th (I don't like endos!). So I figure the best I can do is eat well and keep riding.
