Hello coolsocks: I noticed this is your first post here on PC. So... welcome to Psych Central. The addictions & the eating disorders forums may be of interest to you. Here are links to these forums:

I'm sorry I don't think I have any suggestions for you myself. Hopefully there will be other PC members who will have some ideas they can share. In the meantime, here are links to 7 articles, from Psych Central's archives, that (hopefully) may be of help:
