There's a thread in the General Exercise forum ( http://forum.lowcarber.org/showthre...&threadid=32311 ) that gives a lot of information about thermogenics like Stacker 3. One of the things they talk about there is that they're more effective if you do them for a couple of months, take a month off, then resume them. I've only been using them for six weeks, so I haven't tried going off them yet -- that happens on the 15th.

Stacker 2 worked to get me out of a stall -- I was stuck in the upper 170s, and I'm now in the low 170s. Sorry I can't be any more precise that, but I'm terrible about keeping records of weight loss.
