showers, parties, gatherings

So, so far my ability to avoid snacking like a crazy person at parties, showers, gatherings, etc.

I don't know what it is. Before i've gone to parties, showers since i started this new path, i've eaten a good lunch or dinner before going too. It's like i see all these foods that i don't eat now, and i can't help myself but just to eat, eat, eat. I feel like my stomach thinks it's never going to be able to eat food again.

It's really aggravating for me, and frustrating not to mention, stupid. UGGGH!

Any idea/thoughts peoples?
