I'd be willing to bet your estradoil levels are through the roof.
IMO, I would strive to lose the weight threw dieting and exercise first before I started HRT. There is alot of science backing up theories that overweight people are addicts, and food is thier drug of choice. Something you might want to fix and overcome before you start messing with hormones.
BTW, this program they want you to start is bogus.
