Have a hard time to get to sleep at night?
 

Maybe it's because you're using your computer late at night.

I've noticed that ever since I started using my laptop in bed, I have a very hard time falling asleep.

I get in sleep mode like charm if i watch some video on pc late, only problem iz buzz of the sourond system, i shut down pc with wireless mouse, but to unplug them i need to go up from bed :(

I just collapse into an alcoholic stupor at various diff times during the day, so no real big issue...

EDIT: Except for when I am driving that is

Soma and it's good night. :)
