Like "I cannot speak to the medication issue, having never used Metformin. I've been going to the gym almost a year and a half. I walk on the treadmill, then do weight training( no pool at my gym). I know I'm stronger as I have gradually increased the amount of weight I'm able to move, and it does feel good. It hasn't helped me a lick with any weight loss and I'm tired of fighting it. I continue to go to the gym because it does make me feel good and I recognize that it's good for my joints etc. I still hope (in vain, most likely) that someday the weight will start to come off. For now I'm just going to take care of the diabetes and kidneys. I tell myself if I'm meant to lose weight, it will happen, but I really don't hold out much hope anymore."
