I have Lupus, and suffer from Raynaud's too. Eating a healthy diet and getting exercise has helped me a lot. Age helps too, I think! (at least there is ONE advantage to being over the hill! LOL) I am considering joining the Y this fall so I have a place to workout over the winter. The winters here are mild, but not mild enough! I love doing water aerobics, as we have an in ground pool in our backyard, and I would really like to continue it over the winter. The Y offers classes, and has a gym as well.
Are you following any particular diet plan? I am also diabetic, and I follow Sugarbusters. I love it, as it is easy to follow, and has worked well for my diabetes control.
