Ergot(tamine) is not very effective for Cluster although it was used for many years, since there were no alternatives.
Educating yourself is essential if you don't have access to a doc with good headache experience.

I'd suggest the second book because of the price.
MANAGEMENT OF HEADACHE AND HEADACHE MEDICATIONS, 2nd ed. Lawrence D. Robbins, M.D.; pub. by Springer. $50 at Amazon.Com. It covers all types of headache and is primarily focused on medications. While the two chapters on CH total 42-pages, the actual relevant material is longer because of multiple references to material in chapters on migraine, reflecting the overlap in drugs used to treat. I'd suggest reading the chapters on migraine for three reasons: he makes references to CH & medications which are not in the index; there are "clinical pearls" about how to approach the treatment of headache; and, you gain better perspective on the nature of headache, in general, and the complexities of treatment (which need to be considered when we create expectations about what is possible). Finally, women will appreciate & benefit from his running information on hormones/menstrual cycles as they affect headache. Chapter on headache following head trauma, also. Obviously, I'm impressed with Robbins' work (even if the book needs the touch of a good editor!) (Somewhat longer review/content statement at 3/22/00, "Good book....")
HEADACHE HELP, Revised edition, 2000; Lawrence Robbins, M.D., Houghton Mifflin, $15. Written for a nonprofessional audience, it contains almost all the material in the preceding volume but it's much easier reading. Highly recommended.

Anti-depressants are not useful for Cluster.
