Is it possible to have a food hangover?

I feel so terrible - I think I may have a food hangover.

Rich's parents were here for the weekend so we ate out heaps - now I feel so bad - like actually physically sick bad not guilty bad (although I do feel guilty bad as well).

I'm pretty positive I would have gained this week with all the bad food I ate - but the worst thing is - I did honesty try and make healthy choices - but eating out healthy is a lot different to home made meal heathy.

I felt bad last night and I still feel bad this morning - bleh....
