Cory,
I echo what CHFather, DD and Spiny said, and will add...
This isn't a strategic military mission!, where you send in a few of your men to see if they can kill the enemy, and if not, you send in a few more. Killing the Beast is like D-DAY!! Send in everything you've got, then send in some more. Hit it from all directions, all at once, from the air, ground and sea. Use every available weapon in your arsenal to utterly destroy it! Anything less than that, and you're just teasing the beast.
Abortives:
O2 should be number 1, used with every attack.
Energy drink too
And any injection meds the doctor gives that are safe to take.
Preventatives:
Vitamin D3 regimen at full dosage
Magic mushrooms and/or RC Seeds or doctor meds
Melatonin
Post-Attack:
Water, water and more water
Coffee is nice too
Chocolate
Watch out for those land mines (triggers) and avoid them at all costs.
Once the dust settles, and the war is won, you (i.e. your husband) can back off and experiment to find what works, what keeps them away and what stops them. But from what you've described of where he is at the moment, I'd be throwing anything and everything I could at it. Get in a better place, then reevaluate what works and what doesn't.
Just my 2 cents.
I'm super excited about the progress you've made, you're so on the right track. This is a great group of people, isn't it? Wish I could bring every Cluster Head in the world here and we could help them one by one. I spent so many years in pain going the doctor route, when I should have started my journey here.
Also, something that occurred to me while reading your post. From a very personal point of view, I'm delighted that I've been able to contribute and help. I can look back at my years of extreme pain with a sense of satisfaction. I've beat (am beating) the beast, and more than that, I've lived through it to help others.
Hang in there. You are not alone.
