Absolutely! Lost about 20 pounds when I got into this, and whenever my weight starts to go back up I declare a crash program, shave down and spend a lot of time at the pool....I find the old Beverly Hills diet is a great shock weight loss program (you eat nothing but a pineapple the first day) and try to eat like a girl after that: Special K for breakfast, cottage cheese for lunch and lean cuisine for dinner. When I'm dressing I walk a lot (shop till I drop) and curiously, I only feel the urge to smoke when I'm dressed, a great way to curb my appetite.
