I know this well. 20 years or more I've suffered 1-3 times a day, every day for 3 months at a time, 1-2 cycles a year. Wake me out of a sound sleep, frantically fumbling for an imatrex shot. I'm just starting another cycle (and they'll only get worse until they, like, peak for me) and I want somebody to feel bad for me. 😕 every Time I feel the onset I say, "I can't do this again, I can't go through this again.) terrified. I've saved up about a hundred shots since the last cluster but I don't imagine it's a great idea to use them every day for even a month. Maybe it's ok to, idk, but when they come, and I know I have a shot, I'm using it.
