++ What Jon' said.
Gabapentin sometimes helps, but many people find the side effects hard to take (general dullness, lack of coordination, etc.). I agree with Jon''s hesitancy about verap and gabapentin at the same time. And I agree with him about browsing around the site -- maybe start with the ClusterBuster Files section. (If you're going to be using Trex, there's a tip on the second page of those Files about how to get 2 or even 3 injections from one injector. You can also get trex in vials, with syringes, and measure out your own dosage. 2 mg is enough for most people; 3mg is almost always plenty.) If you have a question about a specific thing, you can try typing it into the search bar, top right.
Oxygen (which should be prescribed to you, but if you're in the VA system (I don't know how it works for active-duty spouses) might not be because the government doesn't recognize O2 as a CH treatment even though all the medical literature puts it at #1). There are other ways to get O2, but first ask for a prescription.
Like Jon' says, do the D3 regimen. http://www.vitamindwiki.com/tiki-download_wiki_attachment.php?attId=7708 (It was invented by an ex-Navy guy.) Drink down a cold energy shot as soon as you feel an attack coming on. Many other things to consider, but those are all good places to start.
