I feel your pain. I have insomnia also, and I know the 'late night cravings' you're talking about. Thank goodness I have a treadmill, because I don't really trust the side of town I live on to go walking/running at night. I have been having a lot of trouble with my bipolar/insomnia lately, and my sleeping schedule is messed up like yours is right now.
looking for the same advice.
I downloaded the program fitday the other day, and have started keeping track of my exercise and food intake. Hopefully that helps, also.
..and yes..we WILL lose the weight!
