I can't speek of speedier ways, I was offered medication because of a metabolism issue, btu it didn't help via regulating me, it only amped up my thermostat - speed, basically - so I declined.
Exercize - small, varied exercise will help alot, I think - and just dont fret.
I have after a long time come to peace with the fact that I am losing slowly, but the sleeve will help me stay on track, and I lose inches even when I dont lose pounds.
May I suggest you find things to keep you occupied? Painting, taking a class, or rediscover the things you lost as you gained the weight? I have took up swordsmanship again, and contact juggling, poi and hula hoops - I lose hours and build up a sweat, and the days just roll by...until the day I went into Old Navy to buy a summer slip, and had to get a 12 instead of the 14 I picked out...
Namaste.
