That's not necessarily munchies....I did that once before I ever smoked, with a 1lb bag of almonds up all night cramming for finals in HS.

Really I didn't intend to stay up all night studying...I spent most of the night trying to pass almond paste through my sphincter. And then sitting uncomfortably and tired through all the tests the next day.

I think that's an anecdote more related to Binge Eating Disorder, which is often linked to ADHD.
