Just thinking

I have been at it for almost two months now, and Weight Watchers appears to be working. I know, however, that anything I tried would have worked if I did it. The problem is the mind set, getting to the point where you say, "All right, I'm going to do this." Once I decided that I was going to do it, I did. When I hit my second no-lose week in fewer than eight weeks, and knew I was following the program to the letter, I decided it was time to kick in with the exercise. So I did it.
No, it's not necessarily easy, but it is possible. I'm getting up at 5:30 a.m. now so I can get to the gym before work. When I start teaching, I will have to go after school, but I will do it.

My fear is that I will lose the enthusiasm I have now, the commitment to get the weight off and be healthy. I know myself very well, and if I lose interest, or the will to make it work, I will go back to eating far more than I should. Once the commitment is there, and as long as it stays, there's no problem avoiding McDonald's, because going in is simply not an option.

Any ideas for hanging on to the commitment?
