Unless I'm doing something that keeps me awake (playing or reading something exciting), I usually fall asleep as soon as I'm comfortable. Sometimes I could be playing games on the bed and wake up with the game still on...
Usually very long, I get home and shift around in the bed forever before getting to sleep, on a rare occasion I actually will pass right out, but that's usually after a day where I got no sleep or did a lot of stuff. This morning was one of those rare occasions, I came home and was struggling to keep my eyes open for a trade on ACNL. XD As soon as it was done I passed right out.
It really depends for me. Sometimes, I fall asleep right away. Sometimes, it takes a good 10-30 minutes. Then, there's those nights where it takes me an hour or 2 just to sleep. And rarely, I have nights where I'll just lie there awake for 5+ hours, 'cause either I'm not tired or I heard some freaky sound and paranoia kicks in (thanks, paranormal investigation shows).
normally it takes about 1 hour of lying on bed if i try to force myself to sleep and if im stressed out, it takes more than 1 hour like 2 hours or more. but if im really tired its just a couple of minutes.
too long. i use my ipad in bed which probably makes it harder for me to sleep but usually it helps. because i cannot sleep if it's pitch dark. i have to have some sort of light for me to sleep
I only sleep when I'm extremely tired and can barely keep my eyes open, so obviously it doesn't take me very long to fall asleep.... Now forcing myself to sleep because I have things to do the next day etc, is a whole other story.
