Here's an idea for sleeping better. When you can't sleep, it is usually your busy mind thinking about lots of random things uncontrollably. Tiresome, I know. Basically it means your mind is controlling you. That is a problem, because you are supposed to be in control of your mind, not the other way around. Most people are not in control of their mind and suffer a lot more than just loss of sleep. This is not the ideal way to live. The most successful people have learned to have more control over their thoughts. I learned the best self-mind-control techniques from a book called: "The Power of Now." I recommend you read it. But, to help you out tonight, I'll tell you one simple way to practice quieting your busy mind and get you to sleep fast. It sounds too easy, but it really works. Don't judge it until you try it.
Here's what you do: Simply, observe yourself thinking. Mentally watch yourself think. That's it. Literally become a spectator of your own busy mind and watch what happens. You will soon realize that your mind will stop spinning you around in circles all night, but a few minutes after you mentally become the spectator, it will stop and you will be in control. Control feels like being completely present--absent of any thoughts unless you choose to think on purpose. When you mentally observe yourself thinking uncontrollably, it is almost like you and your mind are two different people. One quiet one (watching) and one busy one (thinking). When you become the watcher, the thinker quiets down very quickly and your mind will start to relax. It is a wonderful thing. Just try it and let me know if it works for you.
By the way, I love paintball too but haven't tried a tourney yet. Looks fun. I shoot a DM5 with a carbon barrel. Good luck!
I don't think it's necessarily a bad idea to stay up the night before, but I think it would be better to cognitively restructure your thoughts to get to the root of the problem. Read these boards for some solutions and see what works best for you. I really don't like the idea of purposely jacking with your sleep without getting to the cause of your sleep problems--your thoughts. Probably if you want sleep properly I think you should go for Derma Sleep Patch to be applied on specified body part. It is drug free. I think their site name is www.dermasleep.com
All the best.
