Thanks Mammac. One of the reasons I went to the doctor in the first place was because I was having trouble sleeping. The bones in my legs, hips, and back start to ache horribly after 2-3 hours of sleeping on one side, so I would wake up a few times during the night in pain and have to turn over. I knew this was obviously a verrrrry bad thing. The doctor said that my weight and BMI are considered underweight, and I need to gain a few in order to get some more "cushion" on my bones to prevent sleeping discomfort. I also can't sit in hard chairs for long periods of time because my "butt bone" starts to ache. I don't want to be bony!! I just want to be fit and trim I agree with you that weight training is a good idea. I started going to a 30 minute beginning strength class twice a week. I also plan on consulting a nutritionist to make sure I am I don't have any vitamin deficiencies and I'm getting the right amounts of calories/fat/etc.
