will power

I am frustrated because my will power seems to have deserted me at the moment.  Last night I felt horrible because I think I ate too much or something.  Today I didn't eat breakfast and had lunch with my grandchildren and then fell asleep late this afternoon and woke up at 9 p.m.  Ate dinner, but not alot and my stomach does feel better tonight.  I have never weighed this much and I really would like to lose 60 lbs.  I know what I need to do but am having a hard time getting out to walk.  Tomorrow morning I am going grocery shopping and planning to be stricter on my diet.  I am on Weight Watchers which I have always heard that it is a great plan.  I just heard about the Dash diet, does anyone know about that diet?  Marie
