Yea I too get extremely tired and can literally sleep for 14+ hours and still want more after eating gluten.
It is the only real symptom i get from it. I have been to groups and normally celiacs have other symptoms that dominate there complaints, so I'll often assume i must not have it and go eat some gluten, then bang 3-4days of extreme tiredness.

I can relate to these experinces, especially the length of time for the alcohol to be removed from my system.
Last new years I had a breath tester with me (good quality one), and at noon the next day i was still twice the legal limit while all my mates who drunk as much as me had zero breath alcohol. At 5pm that evening i was still blowing over the limit...
