Haven't Been On in a few.....

I think it's actually my guilt! After such a great start, last week I only lost 2 lbs. Still a loss, but I'm very overweight so I expect it to come off a bit quicker than that....and i've been slipping a bit....I find it hard to get enough water (really a very simple thing if you think about it - but maybe that's the problem, I don't think about it at all) and I've been eating out, not ordering the best things, and snacking on unhealthy things at home! Why is this so hard for me?
