watching tv in bed trains you to not go to sleep while in bed. you shouldn't do anything in bed except sleep/bang and you'll be more likely to be able to sleep while in bed.
Knock one out Only kidding. I stay awake until I am really tired otherwise I will be laying in bed for hours. Usually on the net or watching tv. If I go to the gym after work I am usually tired by midnight anyway.
It's been a long long time since that ever happened to me. Most of the time I'm so tired I fall asleep within 5 minutes of hitting the bed. I literally try to be awake as long as possible
I do a lot of things. I get out of bed, walk. If it doesn't work I start reading some boring book. If it doesn't work either, I smoke and design...
I typically watch TV. I rarely get out of bed if i'm not sleeping well because usually i'm just halfway between awake and being asleep. If I don't feel like going to bed and sleeping (i'm a night owl)... I will either play games or visit forums and try to do some link building for my website. Sometimes I will design a website if I have a new idea in my head.
