I have a cheat meal once a month (only exception is when im cutting - usally i go 6-10 weeks on a cut) I have kind of planned them to fall around events Christmas dinner, Thanksgiving lunch, Birthday, etc.
My favorite cheat meal is on my birthday. This year large Domino's sausage Pizza with 2-3 slices of Juinor's cheasecake.
I fucking love pizza, to bad that shit will kill ya.
