I have a much simpler solution for you, and it doesn't involve hypnosis:
Eat the donuts... Really eat lots of them. In fact eat nothing else.
Start with a dozen for breakfast. Keep a box by the desk for snacking. Eat donut holes for lunch. Have a handful of eclairs for dinner.
You must eat only donuts. No meat, no vegetables, no fruit, no bread. Only donuts, and lots of them.
I figure in about 2-3 weeks you will be cured.
