Your doing really well there, 12lbs in 12 days is quite an ambitious target, but if you don't try you have no chance of succeeding.
I have done vlcd's in the past and although the first week loss is great if I can maintain 4lb a week thereafter I am pretty happy. I snuck on the scales this morning and am down to 11 5.5, so not doing too bad.
How about you so far, or are you resisting the daily weigh-in!!!?
