NO SLEEP

So I was so ready to start the P90X system, but when I woke up my head was killing me. I have had migraines my whole life so I already knew it was going to knock me out all day. So I will start today. I am so tired today, I slept from 5:30-6:45, I HATE INSOMNIA!!!! I don't sleep about 3 nights a week. Any suggestions on how to sleep with out using medicine let me know.
