Hmmm, that sure does seem strange!  You need to speak with him and ASK him WHY he does not want to give it to you anymore.  Is he planning on giving you something else?  I would really hate to see you find another Dr. but if he does refuse to help you out, then get the phone book out and start looking.  Please though, you really need to ask him what his plans are in treating you first.  Just maybe he wants to try another medication.  I wish you luck and try not to get stressed over this yet.
