There are some rules, not necessarily theories, I hear passed around with CH that I don't agree with.
1) Smoking: Listen, if this were the 90s, the Eastern Shore of VA, $10 carton days (when I was coming up) it would be dim lights, thick smoke, and loud music in this bitch. I'd be smoking like a choo-choo. There appears to be an alarming correlation between those with CH and former smoking habits. That stated, it never triggered (my) CH. If it does not cause your CH, who cares, smoke. Your gonna die at some point.
2) Drinking: This one is difficult. For some reason, beer causes massive headaches, but with moonshine I am okay. I make moonshine and drink accordingly. For some, it is wine or those wine benders. I seldom drink, the majority of the time I use the liquor as a trading offer for something else. Bottom line, I do say with alcohol to tread lightly and stay away if getting hit. I'm neither chronic nor episodic, and I don't know how to explain my headaches either, in my circumstances I wing it.
3) Sex: There can't be a God if you get your rocks off and have a massive migraine and/or CH. Honey, that ain't natural. I get myself in trouble here all the time, if that shit happens, we all have needs, and even at 90, that is why there is Viagra-I rest my case. Get some Narcs, and abort with opioid analgesics. I'm sorry that ain't right, and it's cruel. If in a drought, there is the champagne room and sites like Backpage. And since I dug this hole, I don't see why women even date men, as hot as women are. Lord have mercy, especially when hot to trot.
4) Drugs: Party on man. Again, I get in trouble, but if you can control it and it is not a trigger-go for it. Uppers, downers, and turnarounds put me in an 8-year intractable cycle of hell. Unlike most, however, I'm all for the coke and whiskey, fast women parties, and am not afraid to put that out there. The problem is that for most, most drugs appear to put you in a cycle you can't get out of. Getting off of Barbs, Benzos, Uppers, Downers took 1 year of shakes, convulsions, seizures, a few near-death experiences, and a grand mal seizure. And, I now have Tardive. Your choice. I'd do it all over again. What a fucking rush. Talk about kickstarting my heart, I made Ozzy Osbourne and Motley Crew Habits look like choir boys.
5) Abortive Medications: Oh hell no. Go ahead foment wicked rebound headaches. It's your choice, but I had every headache specialist admit off the record that you are best to avoid them. If Oxygen does not work, as in my case, I feel for you. Prophylaxis is paramount. Again, it's your choice, but that Fioricet at 180 counts, and banging 3 DHE a day does more harm than good. Oh, and shooting up Keterolac 1 or 2x per day.
I don't know, I admit to being on the outer fringes but, everything is case-by-case. The intention of this was don't live your life around CH: live your life and adapt to the bullshit that CH brings with it. It is not easy. I am convinced that you can determine your triggers, mitigate them, and then find prophylaxis. It's not easy, may take years, several doctors or nurse practitioners, even functional medicine. Most importantly, you need to be your doctor first: read, research, and find what works for you.
I don't think anything can be categorized or programmatic at times. Everything is subjective to the situation at hand, and the person experiencing the headaches. Good luck.
