My doctor said "you have to earn your sleep". I had the same problem until:
- two pieces of fruit per day
- two portions of vegetables per day
- half an hour of outside sunshine per day
- twice per week exercise until you sweat
- no sleep during the day
- get out of bed every morning around the same time
- no processed food!
Kinda funny seeing this reply side to side with the "I just took LSD" one
I wish your doctor's advice worked on me. I'm in the same boat as the person you're responding to, and I follow all this advice as well.
