I'm doing it from home now as there isn't a class convenient enough for me that's worth going to really. Its working for me, Im losing about 2-2.5lb a week and this board is definitely helping with ideas, motivation etc.
I dont think I would have managed if I hadn't already done SW as a group before though, as the online direction and support is non-existent IMO. I probably wont renew at the end of the 3 months and its definitely not worth the money, but then again if it works it works I guess.
