has the doctor said anything about an underlying cause...like have you had this all your life or did it just start up? could something else be triggering this...since it seems you only get this at certain times a year.......possibly it can be curable....i know my doctors never cure anything they just give me stuff to live with it i am always doing my own research...and end up by helping myself.....have you tried going to any local health food store and asking the owner if they have heard of this?

sorry don't mean to berate you with questions,,,i just have strong feelings when people are stuck with something and have this hopelessness typr feeling...too many times over have i witnessed people being "cured" and doctors saying theres no way you will ever get over whatever it is they had.
