Congrats to you. You're learning behavior modivication. That's awaome.
Set yourself short term goals & you get a prize. DO NOT use food as a prize.
Get a manicure, a pair of shoes, 1 makeup product.
If you can't afford do go out & get prizes. Do it yourself. Give yourself a mani & pedi. Stay in side 1 night & give yourself a day of beauty. (a nice hot bath w/ candles & oils, give youself a facial; steam up some camomile tea & steam you face with it, give yourself a mani & pedi).
Also, you may want to take pics of yourself 1x a month to see your progress. You may not lose weight on the scale but you may be losing lots of inches.
Hope this helps & keeps you on track w/ giving youself rewards.
Good luck & keep it up. You're doing awsome!!!
