You just have to be organised. I shopped once a week and went straight home and weighed everything and put into little plastic lock bags so it was easy during the week. The first few days are tough but once you're over that you don't even feel hungry. DH supported me by cooking his own meals so all I had to worry about was me and not being 'tempted'. Maybe just go to the first session where they tell you all the info and then decide. I found the people really supportive and felt that I got good value for money. Good luck!
