yep, i agree. i think the thing to focus on here is the post-workout aspect, not the "about to go bed" aspect.
as jules said, carbs are essential in a pwo meal - which should ideallly be a drink, not a meal, for quick absorption.
remember too that carbs take different forms. the carbs you ingest pwo should be easily digestible - maltodextrin and dextrose are the most commonly recommended. i mention this because in talking about carbs before bed, we're not talking about pasta - nothing complex.
and these carbs you ingest pwo will be quickly and easily absorbed by your system. have a read of this article by john berardi. it will answer your pwo questions, and should make you more relaxed in the context of doing all this before bed.
