I've done that a lot the past days - I'm surprised I haven't gained weight, honestly.
I ate a tiny slice of cake this evening, a lot of pizza the past 3 days, many, many small meals over a course of 3-4 hours (I'm always hungry) and I feel so terrible, I try to exercise as I should or more the next day.
But I do think you should just stick with that you do usually.
One time of eating too much isn't going to do anything wrong long term.
