Clusters are no joke. I mean, literally no joke. I'm sure you spent the better part of the day in bed nursing a bottle of Tylenol and ice/heat/a humidifier. I feel so bad for you. </3 I've been a victim since 12, graduated from OTC normal pain-killers to straight up aspirin (destroys your stomach) and then went up to triptans after my doctor fought with the insurance company for a month.
After two of those, developed an allergic reaction and ended up in the hospital. So, my sub doctor put me on 400mg B2 (Riboflavin) and a Multi, I've gone back to living most of the way. At least I'm not loosing two/three weeks of healthy functioning to thunderstorms/dry lightning. I'm pretty happy it's gone down to every once and a while, once a month at max.
Getting my vision checked and getting a pair of glasses also helped; turned out I was living with astigmatism thinking it was 'normal.' Haha
