None that I know of specifically, but when I've taken any benzo 2 or 3 days in a row it has tended to make me somewhat more susceptible to migraine, so I try not to take it 2 days in a row anymore, and figure that avoiding it once a migraine is already in play is a good idea too. I've never heard of anyone having that reaction, but the list of things can be involved in triggering my migraines is long. Sometimes just breathing seems to do it.

I generally take less than 2mg xanax (or equivalent klonopin) in a whole month, as sparing as I am with it. Only when I'm having an extraordinarily difficult time getting to sleep or know I'm going to be in an unusually high stress situation. In retrospect I really should have taken it early Xmas day, driving my mom and her husband an hour each way through New York City, arguing with me and each other the entire way about which highways and tunnels each of them thought I ought to be taking despite that the GPS was already continuously updating where the least traffic was going to be. Good god. I'm still recovering.
