Having Trouble Staying Motivated...

I'm trying to lose about 15 - 20 pounds to get back down to my pre-college weight.  Trouble is, I keep getting side tracked.  I feel like every time I have a couple of good days of diet and exercise, some excuse comes up and I overeat.  Any suggestions for staying motivated and on track in the beginning?  Thanks!

I have the same problem!  I had a great week three weeks ago with both my workouts and my eating.  But for some reason, I keep finding excuses not to work out or to eat something that I shouldn't ever since then.  I'll do good for a couple days and then I get off track again.  I want to lose weight.  I want to reach my goals.  But I seem to be my own worst enemy.
