I found that the 2 times I was on Met for 2 weeks (the longest I could stand it) I lost 14lbs both times (and gained them back) then when I started my Atkins Induction for the last time (and am still going - just prego for 6 more weeks) I lost 14lbs as well. I have determined that while I was on Met I was eating "lower carb" to avoid the symptoms and so am not convinced that it was the Met that made me loose the weight. Good luck to you and congrats on your loss!
