I used to have the same problem mate, used to eat sooo much when i was high, your minds saying eat and your stomachs saying no more!! I also found it killed my buzz aswell. I started drinking coffee, I found this was pretty good at surpressing my appetite. I reckon will power would help aswell, but we all know how hard it is not to eat when your munchied, especially when theres a fridge within walking distance thats brimmed with amazing food I recommend trying the coffee thing, thats if you like coffee, if not the only thing i can suggest is just trying not to eat, however hard that may be Hope this helps man...

Peace
