Hi I am new to this form. I suffer from Migraines and Cluster headaches. I guess i am lucky that my cluster headaches only happen once a day for no more than 3 days but they last for 3 to 5 hours. Currently the only medication I am on to stop attacks is Diltiazem 120mg twice a day. I tried Mushroomes at low doces with no extended relief other than they stopped the headache. Does being on Diltiazem cause the mushrooms to be infective? Or do I need to take a larger dose?
