Hi there,
I think it really depends on you. You look like you have already done an excellent job loosing weight, so if you already have the momentum going and are good at loosing without the dicipline of meetings than go for it!
I enjoy the meetings a lot! I enjoy talking and meeting to the other people who attend. I enjoy being around others who are loosing. I need the dicipline of knowing that I am accountable at the meeting.
I do think though, that I COULD definately do this on my own. It isn't cheap, but I definately look forward to my meetings each week.
Having WISH is like having a huge meeting. You could probably easily do it on your own if you have the willpower! I have started posting my weekly WW meeting topics on Monday nights. I didn't have a meeting this week because of being on vacation and it was a holiday. Look for it, this way you will get the benefit of hearing what they discuss at a meeting.
Good luck with WW's. I love it! ALOT!
Melanie
