I know that this seems to be a little off-topic, but I think that it helps with Photoreading. Do you guys know how to sleep less? I read somewhere in the forum that someone has successfully reduced his sleep hours from around 8 to around 3 hours. This is my dream. I usually sleep at least 8 hours, and If I must wake up before completing the 8 hours, I feel bad the entire morning (and sometimes the entire day). I want to sleep less because there's a lot of things that I want to do (Photoread a lot after taking the seminar, for example

). I know that the brain needs no more than 1/2 hour(s) of sleep.
Someone can help? I don't mind If it will take months before learning how to sleep less. I need it bad! 
Thanks.
