Topamax and oxygen

I am almost 41, and have had migraine headaches most of my life which I could manage with 800mg of Naproxen Sodium, or a Norgesic Forte, and when Imitrex came out, I could just administer that. Six months ago, my headaches got so frequent that I had to start taking my Relpax (similar to Imitrex) and/or Fioricet more than 2X per week. According to my neurologist, this is a no no, as both of those meds can couse rebound headaches. He started me on Topamax, 50mg per day. It did nothing. He bumped it to a 100, nothing. Now I'm a 200 mgs, I am still have a migraine in left temple as I write this. I have the tingling, the daytime sleepiness, but my mind is fine, and my appetite is just swell (regretfully). What the hell am I going to do now? Ask him to bump me up to 400 mg? Now I have these headaches every "F"ing day, and I can't take anything. I just have to suffer.

Topamax is NOT working!!!!!
