OKAY!! I am tired of not losing for a while! Anyone else?

Okay, I am getting mad at my little body's furnance and want it to start the scale moving again!! I suppose this is my first REAL stall. I am still at 80-82lbs! I lose like 2 lbs a week now, or less. I have got to do something to get it going. I am now 198lbs, which is great, below 200, happy bout that, but its been the same number now for a week!! So, any ideas to get it going? I have been watching my carbs, and tonight I had some grapes, so I can stay regular, hmm hmm, gotta keep everything going, but the grapes must have been about a week old, and when the "ferment" a little, I dump, higher sugar content I suppose. I am having fast heart beat now...racing, so I know I will dump in a bit. What can I do to break this? I am about 1 1/2 weeks from being 6 months, had hoped to be 100lbs down by then, can't do 20lbs in a week! ha ha Anyone else? Got solutions?? Thanks! Deb
