i started playing foosball as an alternative to world of warcraft, which did give me bad insomnia. but come to think about it... i really haven't had much trouble sleeping since getting off the "crack"(warcraft). although i am a expert sleeper, i am not a sleep expert. so i would defiantly look for sleep tips from google or real sleep experts, they will help u as they did me. my advise would be : Dont lay in bed for to long while not sleeping! u are training ur body to think its ok to be in bed but yet not sleep. clear ur mind, not flood it with competative thoughts that might release adrenaline to work against u. to sleep i tap my feet while counting from 1-10 rinse and repeat. this usually takes enough of my attention where i cant focus on the game.find something that works for u
its seems to me like this is going to be another aspect to ur game. u have thing u do to "get u in the game", now u might have to work on some tools to get ur mind "out of the geme". ur body and mind have to be primed to sleep, not "go mode"
foosball wise how does ur routine go? do u theory craft early thinking of what u will practace, then practice, reflect, practice again, then reflect for the rest of the night or until u practice again? this might keep the flood gates open continuously subconsciously. if u are reflecting while u should be sleeping then mabe u feel like u could have done or thiought more about it(mabe increase ur reflection time to justify sleeping to urself). or mabe cut out reflecting after ur final practice till an hour or so before ur next practice. it seems u have to square away ur reflection time before bed time and tell ur self... ive theorycrafted for an hour or 2 and thats it for today(be content)! then prepare for sleep, leaving the game till tomorrow.
sorry bout ur insomnia! it drove me nuts
