Hello, welcome, sorry you need to be here. Regarding your doctors' frustration, when I finally (40 years worth) found a really good doc who listened and investigated, he said right at the start that doctors hate migraines because they don't know what causes them and don't know how to cure them. The important thing is to be open to as much info as possible, and see what fits *you* -- we're all different and the only thing that counts is what works. An important tell-talle on docs is whether they want you to know only what they tell you or (like my new doc) appreciate that you can research stuff on the web. Good luck. Ron
