Since last Monday. When the kids went back to school the first week of September, I had vowed that I would start losing weight. I bought low fat, low cal stuff. Watched what I ate and starved! I was hungry all the time. I found myself with the shakes. I'm hypoglycemic. I did not do well at all. I lost a pound and gained it back several times. Anyway, I started Atkins a week and a half ago and I lost 10 1/2 pounds already! Yee Ha!
