For years I took Topamax as a prevent, but a few years ago my neuro switched me to zonagran (I think that's how it's spelled). He said it was about the same as Topamax without the side effects.
I'm on the D3 regimen seriously (and have been for almost two years without a hit), but I still take the zonagran (just in case - I mean after all the years of being chronic I don't figure it can hurt).
I also take 20mg of Melatonin at night and don't have night hits (been doing that for years and years and it stopped the night hits almost completely.) BUT it took a while to get in my system and stop them... One time don't do it... ya gotta stick with it for several weeks before you say it doesn't work..
In fact most of the remedies we recommend you MUST stick with for a while before you pronounce them useless.
Most of us here have been right where you are -- feeling the world is against us and nobody understands.. (and we have the t-shirts - trust me). But the Vit D3 regimen has worked for me for almost two years (no hits at all) and I've enjoyed every minute of being pain free.
But I will go back to what everyone else is telling you about the narcs.. they only bring on rebounds, cause additions and do NOT stop the CH. A LOT of doctors don't realize this, but it's a fact. A can of Red Bull will do you more good than a hydrocodone.
One time my primary doctor thought he could help me by giving me a shot of some kind of strong narc and he gave it to me. I passed out, but the CH came thru. I was so drunk that I got out of bed and "crawled" to the bathroom to get my vasoconstrictor to stop the pain. But when I crawled back to bed I couldn't get back in it. A friend found me on the floor the next morning. He got really upset and went to the doctors office and brought him to my house to show him what he'd done. That was the last time the doc even thought about giving me any narcs for these things. After that he "listened" to me when I told him they didn't work. We found a "good" neuro shortly after I sobered up.
So I guess what I'm trying to say to you is that we've all been right where you are and have felt that nothing will work, but there is something that will work for you, but you have to give things a fair shot.
Do you have a good neuro? One that will listen to you and knows something about CH? If not -- well, that's the first step in getting help.
Get a NON-breather mask for the O2 and crank it up to 15-25 lpm and do it like Batch tells you (he had to yell at me several times till I did it right).
And you are NOT alone -- we're here and we DO know what you're going thru..
