On the Up and Up

I have been off of phentermine for about 2 months now.  I sort of tapered off of it so I started coming off of it about 3 months ago.  It's scary to watch my weight rise.  I know that this increase is due to a combination of things - first, I knew when I started the low-carb diet that there would be some gain when I started eating normally again (not normally as in how I ate before, but normally as in how people are supposed to eat), second, when I came off the phentermine I started a workout routine so there's some muscle gain involved too.  Thirdly, and this is the part that worries me, I haven't been taking very good care of myself lately.  I'm at 215 right now - 11 lbs heavier than I was just last month.  I eat right all day but follow it up with Oreos in the evenings.  I need to find some other way to reward myself than with food.
