Wendy, before the school year ended, I gave South Beach a whirl, and I thought I was doing so great on Phase 1 after two weeks that I went ahead and took it to a third week. By the end of that third week I had a severe headache, and I finally ate some potato chips (was craving them) and some fruit (also craving badly). My headache went away, and I decided if I ever tried SB again I would not be able to give up fruit. I think that WW Core and SB are a little similar. I can't wait until I can start exercising again, which will be late next week!
