Rewarding myself

Ana and Christy both expressed concern on my tendency to 'reward eat.' When I was talking to Christy, I wondered aloud what I could use as a reward. For her, a trip to the gym or just vegging in front of TV fora few minutes is a treat for her. Honestly, I lead a pretty selfish life. I have few responsibilities and pretty much can do as I please. A trip to the gym is basically a daily occurrence, I watch TV based on my schedule. Since I'm so cheap, I don't want to buy unnecessary things as a reward. Plus my weight loss is much less drastic now do it would be hard to choose a threshold. I've been thinking about this all week. How to encourage myself to make good choices? I decided a points system is best. For every good choice, temptation I don't give into to - I will reward myself a point. Then I'll accumulate points. Not sure what the threshold will be but when I hit like 50 or 100 then I'll allow something frivolous. This way it's like linking the cheap, saver in me with my need to make good choices in my eating!
