I am in a lot of pain (mostly joints, shoulder, etc.) which keeps me up at night. Have always been a restless sleeper, but this is beyond my threshold of tolerance. So far, no meds prescribed have taken the "edge" off enough to sleep. So I find myself constantly going to the fridge. I lay back down and try for sleep - nope - up again and more food. Have gained 30 lbs in three months. Help.
