You betcha! After I weighed under 200 lbs., I had a harder time not giving into the "bad" Sheila that wants what she wants when she wants it. I was feeling good, looking okay, and, hey, I'd lost over 60 lbs. But. . .I never lost sight of my first goal (100 lbs. lost), and I was determined to make that goal no matter what. That was my commitment. It took me a long time, but for me there are benefits in taking that long.
Nylisa has some great tips that might help you along the way. I had to resort to writing contracts with myself to do certain things for four weeks, and I'd actually print, sign and post that contract (for me to see only, however). That's something that worked for me. Regarding the exercise, I've made such a habit out of it that now it feels weird when I don't go to the gym. What helped me in the beginning and along the way when I didn't want to exercise was having my gym bag packed and waiting by the bedroom door and also setting my alarm (I exercise in the morning).
I think that the majority of people get in a funk every once in a while. It's okay to maintain for a while; it's not okay to slide back into the abyss of bad eating and not exercising.
