Wow sorry for the delayed reply, I just saw this thread.
Sadly, I have to give the dreaded "it depends" answer. Seriously, you can imagine how complicated the issue gets with the various foods we eat, our goals, training styles etc.
That's why I feel that an entire book needs to be written on the subject.
For now it's easiest, and effective, to maintain the standard 30-40g protein every 2-3 hours.
BTW-I wasn't hungover, but I did sleep for 14 hours straight when I got home.
