Hi there ~
I am sorry to hear that you have been suffering from cluster headaches
all your life. It is hard to imagine that your medications are not helping. Verapamil
is usually used as a prophylactic medication and Depakote should control the cluster headache attacks. I do not think that you have a seizure disorder
as depakote is also an anti epileptic drug and should have helped with this condition. There are other medications that are helpful in cluster headaches as well. Please consult a psychiatrist
in the area to give them a complete medication history to be able to cure your condition.
I hope this helped. Take care and have a nice day !
