I've been suffering from the same lack of sleep problems due to late night games for quite some time now, it usually feels like im playing UWH in my sleep (along with waking up every 30 mins ),

lately when I get in from hockey (around 11:30pm) i'll make a warm drink, then sit and read a book to try and take my mind off the game that night (rather than mind numbingly sit staring at the television). once I start to feel tired.I hit the sack

it's still not a perfect nights sleep but I feel like I'm getting a whole lot more than I was previously.
