How many of you who have already lost 50 or more pounds have found that it's getting like pushing a boulder uphill to keep losing?

I've posted about my increasing dissatisfaction with Atkins, my main complaint being I have to stay on SUCH a low level of carbs to lose anything, that it's becoming impossible for me to stick to!

I got the expected "do induction over, CLEANLY" advice from some who have lost about 20 lbs in a few months. If you do it RIGHT, it'll work. Also the "foods you crave are the ones you need to avoid" advice. So that would mean I must be allergic to and need to avoid forever, cereal, fruit, milk, yogurt, anything even ARTIFICIALLY sweetened, beans, basically ALL foods except meat and a few select veggies.

I'm looking for some wisdom from people who've been at this a while, no offense to some very smart short-termers, but I need to hear from some veterans who understand where I'm coming from.
