I used to get them, but I started keeping a log of what happened or what I did before the migraine and it helped. What did the log do? Well, the log may show differnt things for differnt people, but mine showed for me causes of strob lights, caffiene, and second hand tobacco smoke. I avoid the lights, completely stopped caffiene, and avoided smoke (helped also by all the no-smoking local bans). Another reason I think I got migraines is because I hated them but felt helpless. The log helped.
