How long can you do it??????

Hey, I'm on day three and staying strong so far... was wondering how long you have all been on slimfast and what can I expect? I know with trying to give up smoking that day 3 and week 3 are the hardest times, thinking it might bne the same with dieting? any advice?

This is my third week, and it's not really feeling any more difficult than the last two weeks.

im on week six not having any probs loving it will keep using meal replacement until i get to weight goal so im looking at mmmm a while
