Hi I've just purchased the My Weightloss Coach for my Nintendo DS. Has anyone tried it? I bought it because they were going fairly fast. I've not opened it for fear the $40.00 I spent are a waste. I've read good and bad reviews on them. But those are of people just trying them for a day not real life like here. What I am hoping is it will remind me since I can take it everywhere with me. Any have an opinion. Thanks
