While I have no serious reservations about the meds your doc gave you, but the package a little underpowered. And I wonder if they plan to continue to see you for a long time, on the assumption that the Dx of Cluster is on target.
Basicallyl, Cluster is not a short term disorder. Most of us have been treating it as chronic condition which regularly continues until well into your 60-70s. We really appreciate working with a headache specialist with whom we have a long working relationship.
Because Cluster has change in its presentation, changes in treatament is not unusual (and doesn't mean a serious impact on us) and benefits from a doc who is sophisticated in working with this elusive condition.
So, if you have the option.....

LOCATING HEADACHE SPECIALIST
1. Yellow Pages phone book: look for "Headache Clinics" in the M.D. section and look under "neurologist" where some docs will list speciality areas of practice.
2. Call your hospital/medical center. They often have an office to assist in finding a physician. You may have to ask for the social worker/patient advocate.

Look for "Physician Finder" search box. They will send a list of M.D.s for your state.I suggest using this source for several reasons: first, we have read several messages from people who, even seeing neurologists, are unhappy with the quality of care and ATTITUDES they have encountered; second, the clinical director of the Jefferson (Philadelphia) Headache Clinic said, in late 1999, that upwards of 40%+ of U.S. doctors have poor training in treating headache and/or hold attitudes about headache ("hysterical female disorder") which block them from sympathetic and effective work with the patient; third, it's necessary to find a doctor who has experience, skill, and a set of attitudes which give hope of success. This is the best method I know of to find such a physician.

NEW certification program for "Headache Medicine" by the United Council for Neurologic Subspecialties, an independent, non-profit, professional medical organization.
Since this is a new program, the initial listing is limited and so it should be checked each time you have an interest in locating a headache doctor.

Cluster headache in the United States of America: demographics, clinical characteristics, triggers, suicidality, and personal burden.

THERE REMAINS A SIGNIFICANT DIAGNOSTIC DELAY FOR CLUSTER HEADACHE PATIENTS ON AVERAGE 5+ YEARS WITH ONLY 21% RECEIVING A CORRECT DIAGNOSIS AT TIME OF INITIAL PRESENTATION.
=================
I'd seriously encourage you to not try and diagnose yourself or try moving from one treatment to another becasue you've read about something here. If you are going to work with a doc, he has to know what you are doing and be in charge of treament. Makding changes can confuse the picture for him and, thereofore, for you.
First step is to confirm the diasnosis with a skilled doc. Secoond, be patient while working out a treatment plan. (During early stages of a new case, the symptoms often change. May take months or longer before a stable picture of our experience develps. Not serious, if frustratsing.)
