Tracy,
I see a couple of people have shared their experiences with you. Although I haven't used Botox, I can tell you that it is quite effective for some, but by no means all Migraineurs. You could probably get more first-hand feedback on our discussion forum. You'll need to register again once there because it's a separate membership database, but you can use the same member name, email address, and password that you used here. You can find our forum at http://forums.healthcentral.com/discussion/migraine/forums.
Good luck,
Teri
