Remeron and ache

I have been on Remeron for 3months, and have went from 125 lbs. to 144 lbs. I want to eat all the time, especially at night. I always feel hungry. I also feel like my legs are swollen, and they ache when I walk on the treadmill, trying to exercise and quit gaining. The depression is better, and I sleep very well, but I am going to really get depressed about my sudden weight gain. Never was this big, except at 9 months pregnant. I am stopping this drug. I also have numbness in my right hand. I don't know what that is from. Last of all, I am more forgetful, and a little OCD now about things.

I have been having difficulty with my legs from the knees down since taking Remeron for over a year. Normal walking is a chore, but let me get in a department or grocery store and I am in such agony with leg pain from the knee to my ankles. It is a heavy, throbbing ache. Pain pills, heat and sleep is the only cure. Never had this problem before this. If I ween myself off them, my migraines come back with a vengence.
