reflexology actually works very well, if not better, when done with the feet.

this sight gives you an interactive hand and foot chart.
as far as curbing you appetite though, i don't know that you'll have much success. I'm sure there's something out there that might help, but i really don't know that reflexology would be very beneficial.
it may help HEAL certain areas or make them feel better, though.
On the chart look for areas like "thyroid gland" or "stomach" or "intestines" or possibly "jaw/gums/teeth."
