I always do the falling asleep mid text message!
And have on a few occasions fallen asleep on the sofa with a pint in my hand, only to drop it all over me and the floor!
My fella was not to impressed with me when I dropped a pint on the laptop he had got me, looked at it, then just walked up to bed!
(sometimes when I have been sleeping on the sofa, I wake up and just dont know what im doing!)
