Have you talked to a doctor about your symptoms? When I first went Hypo and started meds I gained weight, 128 was the highest I got. I've never worried too much about my weight so I thought it was pretty cool to finally have some breasts. I think I'm about your size 5'2 and when I was healthy I weighed from 115-120. Anyways, the weight I gained only stayed for a few months and now I'm only 100 lbs. I'd be very happy to over 120 again. Alot of the weight gain is from water retention...which you will probably lose when you get balanced out. Maybe you need to try a different brand of meds if your body is reacting horribly. How long did you actually stay on the dose when you increased it?
