Chronic Daily Headache

In a completely different topic:
If anyone has suggestions on a cure for Chronic Daily Headache which does not involve drugs, please let me know.
Chronic Daily Headache is defined as a headache lasting 15 or more days a month.
I have heard that in 60% of cases Botox can decrease pain by 50%. Most insurance does not pay for this. I have spoken to someone who tried this with no significant change.
I know dry needling helps (acupuncture needles are used at a greater depth), but I do not know of anyone in Ohio that practices this treatment. I have found an Osteopath who helped, but again, no one in Ohio.
I spoke to someone who had headaches for 15 years! She said she was treated with acupuncture 3 times a week in Peru and now is accustomed to the pain.
