I have done s/b before, and found it successful. I'm back at it, and am halfway through the second week of phase 1.
I am finding it so much tough this time around! Its not an issue of cravings, really, or the south beach flu, I'm just finding that I'm just oddly averse to some of the foods - eggs, meat, cheese, all leave a weird texture in my mouth. I'm also desperately missing convenience foods.
I'm totally whining here, and will just power through, but I am so ready for phase 2!
