How Quickly the Weight Comes

I am SOOO mad at how far I've let myself go! So since I left WW last summer, I have gained 10 lbs. How is it possible to gain 10 lbs in six months??? It's utterly depressing. Granted, there have been things happening in my life such as: 1) Getting more responsibility at work and having to do two jobs - which equals more hours and coming home at later times. Oh and sitting at my desk for hours upon end 2) Officially over 40 and the metabolism is slowing 3) Less exercise and hardly any weight lifting All of these things combined will lead to weight gain but 10 lbs in six months??? That's just downright insane!!! I re-joined WW today and I'm starting with this Simple Start which is essentially eating the Power Foods and no counting. Don't know how that will work but I'll try it. At this point I'll try almost anything. (except crazy diet pills or surgery) I'm now going to take my ass off the couch and do a DVD workout
