So, taking into account Sherlock's incredible mind, I am surprised this isn't canon. Sherlock has sporadic somnambulism, especially when working cases. Add that to the list of poor eating/sleeping habits of his will you.
+ Bonus points if no one knows about it, Sherlock included.
++ Extra bonus points if John freaks out when he finds Sherlock walking around/making experiments while asleep (as if he wasn't a hazardous enough roommate, he has to work on experiments while sleeping!) But, seriously, real sleepwalking is very freaky.
Established relationship or not, your call - I just want John taking care of Sherlock.
+++ And if they end up sleeping in the same bed, all the better!
