Sometimes you just have to give in and eat it! A few nights ago I had a piece of cake and afterward felt like CRAP for eating it.
You gotta give in sometimes 
So I definately understand the initial feeling of being let down! As someone said to me, at least you enjoyed it! All too often we give into things and we don't even enjoy them! And you're doing the right thing by gettting right back on track!! Being bad once in awhile never killed anyone 
But it's okay! Today I'm gonna make up for it! But I'm glad that you guys did too! Damn pizza
Good luck guys!
That's what I meant!
Everyone needs and deserves to treat themselves to something they like. The key is not to over-indulge, and not to make it several treat days in a row!
