Hi, so I slept 10 hours last night but I still feel kinda tired, like my body isn't tired but my brain is. Like I'm acting super dumb and super slow, as I usually do when I'm sleepy. (when I'm not, I'm just plain dumb and slow AS YOU MIGHT HAVE GUESSED) 

My sleep schedule is normally kinda insufficient but fairly consistent and I put effort into keeping it that way.  (2230 plus minus half an hour till 0645, last night I went to sleep at 2105 though)

I don't have insomnia or anything, I usually fall asleep immediately after going to bed. 

What to do, should I sleep more? Less??? Drink more water or something? Fall asleep to rain sounds?????? What do you recommend?
