>Of course this is personality dependent! For me, stuffing myself with sweet, rich food until I felt like I would burst is just one of the best most satisfying feelings ever... if I could just somehow reprogram the mental pathways there......

What worked for me:

Find a flavor you absolutely hate. Be it some hot sauce or mustard or whatever. Top whatever sweet, rich food you enjoy with that topping any time you wish to enjoy said sweet, rich food. This corrupted my memories of "this food was sweet and rich" with "Oh god, last time I did that it was terrible I nearly threw up".

I don't drink alcohol, so I put some rum in my Dr. Pepper. Now I don't drink soda anymore. Ever tried chocolate icecream with mustard? The memory will have you avoiding chocolate icecream like your life depends on it.

It took a bit of self control (actually taking a bite of mustard covered chocolate icecream was tough) but I have such bad memories of the things I used to crave that I no longer crave them. I know they're amazing by themselves but I can't bring myself to partake in them anymore.
