I am doing Jenny Craig right now. I lost 40 lbs on it before I got pregnant with 2nd dd. Since I had not transitioned off it, I gained alot first trimester (20 lbs) when I had to go off JC, then gained even more after dd was born (lots of stress). I thought long and hard before deciding to do JC again, but went ahead with it because 1) I like the food, 2) I need something mindless right now, and 3) I have alot of weight to lose (90-100 lbs), so I have a long time to work out my food issues before I'm going it alone. I know I'm going to have to learn to eat right on my own, and will work on learning how to do that once I've lost about half of the weight I need to lose. I may switch to Weight Watchers at that point. However, JC works for me right now.
