When I lived at home (about 7 years ago) I did Weight Watchers and lost about 2 stone, I have put it all back on though so now I have a fair bit to lose again. I'm going to try and do it myself this time, without going to meetings or anything!
I'm 23, in Hampshire, I live with my boyfriend, 3 cats and 6 ferrets!
NUTBUNI ~ just below the Introductions Forum is a UK forum that you might like to visit; nice to have that home-country connection. There are also lots of WW threads here, and a 20-Something thread too, so you should find lots of places of interest to help you on your new journey. The people here are very friendly and supportive too ...
