Take a look at what I wrote to Hempman666 (next post up). I have had migraines most of my life. When I was 3, a friend tried to murder me with a hammer (I was an annoying brat). Now I've got all these interesting dents in my skull. I can't really remember life without pain when I wasn't smoking pot. I've been smoking for more than 40 years now. Pot works wonders! 5 minutes after toking, the pain goes away. With your early onset, I strongly suggest that you talk to a doctor about getting a CAT scan of your head, just to be safe. Mine had a physical reason, but I still got the scan.
