No kick in the arse, just a
I think that after someone has done SO well for SO long, the worst aspects of being at a higher weight recede and it becomes easier to say, "I'm an average size now, why can't I eat like an average person?" Then there's the diminishing thrill of losing, either because your loss has slowed down naturally over time or because four pounds no longer feels as important as it once did. Add to that a list of comfort foods that you (understandably) ate while you were sick, but that left you with a strong desire for more of the same and it's no wonder you're having trouble.
Maybe it's time for a shake-up--a different plan, or very different foods within that plan. Whatever you usually get as your plan-friendly staples, look for other stuff that's got a similar calorie count, but feels/tastes different. Can't choke down another chicken boob? Get turkey, lean pork, and beef. Sick of sandwich rounds? Get wraps, light bread, anything that isn't another sandwich round. Eat cereal for breakfast? Get a completely different kind or go with eggs for a while. Sometimes shaking it up is all you need to get out of the doldrums.
There's nothing shameful about cookies. Cookies taste awesome and it's normal to want awesome-tasting things. The trick is to figure out how much awesomeness you can fit into your plan, fit it, and then stop. Maybe you could buy a single cookie from Mrs. Field's or a local bakery, then satisfy your baking jones by whipping up some homemade bread or pizza dough? That way you'd get the satisfaction of baking and the pleasure of a cookie without the temptation of a whole batch of the things.
Another thing that helps when I get the occasional "oh, why does it matter?" feeling is doing something I couldn't have done when I was at my biggest. Walk a couple of miles, or jog it if you're up to that (I'm not--yet!
). Sweep and mop the floor without pain. Ride a bike. Try on new clothes at a store you didn't even bother looking at before you lost the weight. Whatever you do, be really, really conscious of how it feels. With 65 pounds lost, I know there's a lot that you can do now that you couldn't do when you started; revel in it. It helps remind you of why it matters.
Your needle slipped the track into its old groove. You just need a little bump to shake it back into the one you were on, I'm sure of it.
