I was on topamax for a while.
What type of headaches do you really have?
Are they really "migraines" or are they something else?
After being treated for ages for migraines, i suddenly took a turn for the worse. Turns out i suffered from cluster headaches. For anyone not familiar, find a sharp pointy object and suddenly jab it into your face below your eye and to the side of your nose.
That's roughly what a cluster headache feels like. Be sure to twist every 15 seconds for a nice added painful sensation. It's caused by a defective nerve that runs along that area.
I became unable to function, sometimes hysterical because of the pain, and pretty much everything in my life stopped. I couldn't goto work or school (college student) and my family didn't know what to do.
I went to the Dr often, getting new pills and new things to try. Turned out that anything in pill form took too long to work - even if i took it at the start of the pain, like the first twinge. Turns out that's one of the indicators of clusters versus migraine - migraines shouldn't come THAT quickly.
I ended up on injectable Imitrex using the statdose system. I was using like 1 shot per day, if not more. It helped a lot, but it was hard on my body, and i didnt like getting stabbed in the arm every day. I was looking like a drug user and running out of injection sites.
I got put on a combo of things from one doctor - but what seemed to help was the Topamax. I had to go on A LOT of it. For a few weeks i dealt with seeing things (like, inanimate object like walls would ripple, keys on a keyboard would shift) and other such problem - all of the mentioned above - but it was worth it to stop the pain at the time.
After the initil super dosage to get the headaches to stop, i went on a regular but high dose. It made me really cranky and irratable after the stupid/tingly effects wore off. Nothing ever tasted good, but i did become functional. The stupidness gets very mellow, and the tingling does go away.
I went on with life, always carried a statdose of imitrex just incase, and too my pills religiously.
One day i decided i was sick of being moody and having to take pills - so i got tapered off topamax.
Turns out i'm like normal now. I could definately tell that i could focus better and my comprehension of things was back at the normal level as i went off it. Plus, i was happy. On topamax i was always cranky and irritable. Like i had a short fuse.
But - it's over now! it's like 6 months and i've not taken a topamax and i'v not used an injectable. Before the events that lead to me going on imitrex statdose and topamax, even in my mild months, i had atleast 1 bad headache every week or so. Right now? Nadda. Nothing, Zilch.
I like to think that the topamax, while i endured it, stopped the electrical activity from that disfunctional nerve. Eventually, it either healed or died or who knows what - i know they can do surgery to snip it and kill it.
But i'm free! Whoo hoo! So, atleast for folks who feel trapped in the headaches - it can end. I thought i was doomed and nothing would fix anything, but i did get mine to end. I still have imitrex statdose (it lasts for like years) that i carry around and travel with just incase - but that's no worse then knowing you're allergic to bees, ya know?
So, chin up

Give the topamax a try for a good period - it takes like a month to really get into your system at the right levels. Give yourself like 3-6 months of being sorta dumbed down and cranky, and then try tapering off. If it doesn't start to work, like lowering the number of headaches and eventually stopping them, of course dont bother staying on it.
Just know that it can work.
