Ha, yes bedtime rituals, I know what you mean mine is chamomile tea and toast. I also have the half sleep half awake thing going off usually after I wake at 4am I never know whether I've slept or not, it's like dreaming awake. Did you injure the front of your head, mine was just above the hairline. I'm always interested to know to see if there are similarities in symptoms - I should start a new thread on this if there hasn't already been one. Sleep is a complex thing I'm told and involves many parts of the brain. The brain itself never sleeps it's always active. I must say I miss that sleepy relaxed feeling I used to get zonking out after a days work.
