I have been on it for about one month now...i wasn't that overweight...i was 5"4 inches and i was up to 168...one month later i'm now 158....and i want to go to about 145....i'm kinda a curvy girl and don't want to get skinny. i find it works really well for me....I have cheated on weekends and stuff and I don't think alcohol is recommended but when we go to the cottage on weekends I tend to indulge....for me it was worth it...and plan to continue.
