In the past if I stayed up unusually late (after 1 a.m.) I would wake up in the morning feeling hungover even if I hadn't been drinking. Last night I was up till 1:30 and realized that this morning I feel just fine, as if I'd slept my normal pattern (I did sleep a decent amount of time, about 6 1/2 hours). Should we give credit to the Atkins WOE for this? I had a very light dinner yesterday and no food during the evening (I was at a long theater production).
