Agreeing with both above! I was put on Verapamil at the start of my cluster journey. Wish I never started it to be honest. I have had no issues with my heart or anything like that but it did mess with the feeling in my legs when I was up at around 1040 mg a day. I have slowly tried to take myself off of the stuff and am now down to 120 one time a day. They say that that does nothing for clusters but I can tell for sure that s not true. I have cut that last dose out and was clean of all verap for about 5 days before I started getting my ass handed to me in a big way and jumped back on it. And because I love to torcher myself I have done this a few times with the same results. When I was new to the cluster game I did not know anything about them at all and like everyone else dealt with it thinking it was a toothache or something. I would get hit ere and there but nothing consistent. I started the Verapamil and an now chronic. I am not saying that is what made me chronic (my wife may say different) but it has been no lookin back since.
Oxygen will be your best friend! 5hr drinks are your side hustle go to that you will tend to keep in your pocket at all times, Vitamin D helps a bunch of people and I feel does bring the pain down a few notches on that kip scale. Busting is not for everyone but definitely read up on it and not in the micro feel good about my life types, you need the cluster type who are trying to achieve a pain free life. Triptans are handy to have around for when you get stuck in a bad place and need that quick relief, and injection is the way to go for that.
Just my 2 cents, I am not a doctor, this is just my experience. We are all different and you will need to tweak it as you go but the people on this site are pro's.
