MarieB,
It's been working great. Honestly, tho, I went on vacation last month and took it with me but never ended up using it and have not gotten back to it yet, unfortunately. Just not quite ready yet. I had lost over 21 inches in 7 weeks on it. You may not have been doing the breathing correctly. In my opinion, it would be worth a try to sit down with the instructional video again and practice more. Maybe you need to take it slower than others. It is a great program and I love it. Just need to get myself motivated again!!! Let me know if you try again. I'd be glad to give any pointers I can.
