I've finally decided to give biphasic sleeping a go. I'm about tired (tired... ha!) of my girlfriend and my father complaining about my terrible sleeping habits. I'm going to try taking my 1.5 at 2100, and my core sleep (4.5) at 0330.
I'll try to use this thread as a blog for the first couple of weeks, if no one minds... I don't want to spam.
Wish me luck.
