I wanna add that I was afraid too and fear of failure made me stop trying altogether. Then it came to me that I have nothing to lose. If I fail, I'd still end up in a better place than where I am now. if I drop from size 18 to size 14, great! I can always carry on doing BFL for another cycle and drop from 14 to whatever. The great thing about BFL is that once you get used to it, you will love it. The first 3-4 weeks are hard, after that things fall into place.
