you are in a dire place, i think most of us have been at. that's why it's important to have an arsenal of remedies ready. like a boyscout you have to always be prepared.
Your List should include:
oxygen
oxygen!!
oxygen!!!
vitamin d3 protocol+cofactors
Tryptamines (LSD, MM, Seeds)
IMHO both verapamil and triptans like zomig are a double edge sword. they take the edge off and mask the cluster but i swear to god those medications made my condition worse. i can not prove it but i am almost certain that that is the case. i have read numerous reports from sufferers over the years that state the same.
bonus as time goes on you will have to up the verapamil, that's how the story goes. and at some point you start feeling the side effects. i felt like a zombie, with severy constipation and waterpooling in my legs, mind you i am a very active and athletic person. it was hell and not worth it.
oxygen and magic mushrooms/lsd saved my life and my sanity. i am forever grateful to this board it's initiator and members.
the drugs doctos perscribe are all offlabel use...make what you will of that.
good luck!
