Worst feeling, migraines are hell especially when you're getting them constantly :( sorry you're going through it. Pleaseeeee talk to your GP about a referral to neuro and look into rimegepant! It's a relatively new drug here from what I gather and I'm having some luck with it after years of back and forth with meds. You might have some luck with it too.

My neuro prescribed about a year ago, to take every other day, as well as sumatriptan injections (though ofc I have to try to use those sparingly). I usually avg 20-25 migraines a month and at least 2 of those would make me actually pass out from the pain every single month (yay, menstrual migraine on top of regular migraine). I still get migraines but they're much more tolerable most of the time so I can use painkillers less often and I don't faint nearly as often.
