Hi Rubyjan,
I'm 5'2" also and have more than you to lose. I'm so determined this year to get the weight off for good!
I've heard alot of good things about weight watchers. And there seem to be so many people doing it--that's very tempting, having alot of company. I really like their cookbooks.
I'm having luck with the Sonoma/Mediterranean diet--that is, when I follow it.
Hope to see you on the threads. Good luck to us all!
