Adding just a little to what Jon said. . . . Here's a link to learn more about the D3 regimen: http://www.vitamindwiki.com/tiki-download_wiki_attachment.php?attId=7708 In San Francisco, UCSF Medical Center Headache Center is led by one of the world's leading CH experts, Dr. Peter Goadsby: https://www.ucsfhealth.org/clinics/headache_center/ It's hard for me to imagine how fresh air helped you, but as Jon says, the highly-effective, no-side-effect standard abortive is oxygen. Lucky for you (compared to many people), I think you can count on seeing a doctor at Stanford or in SF who will prescribe O2. For some people, sipping ice water through a straw aimed at the roof of the mouth, in order to induce "brain freeze," will stop an attack. Any other method that gets that roof very cold (such as holding frozen juice concentrate against it) will accomplish the same purpose. I'm not mentioning drugs or druglike things such as melatonin and Benadryl, since you say you don't want that. If you change your mind, let us know. Since your hits come at night, you could try sleeping in a recliner or in some more upright position (e.g., at a table with your head on pillows on the table).
