Snoopy, Thanks. I am working on filling the questionnaire (its long!). I am not sure how to provide access to the answers though. How is it normally done on this board? Just publish for the whole group or send it via private message to interested homeopaths (prefer the latter though)? Please suggest.

Pat: Thanks for your note. I did not realize cluster headaches can be caused by undertreatment of Hypothyroidism.
