I am a narcoleptic whose cataplexy was treated with Xyrem until I began to develop a severe loss of muscular strength that seems to have been associated with the drug. My physician has switched me to Anafranil, which has worked very well on the cataplexy, without the muscular problems I was experiencing. However, I am now developing severe tremor, which I notice is a common side effect. Will this abate with time, or should I seek an alternative cataplexy treatment. As I work as an analytical chemist, tremor is unacceptable, since it creates severe problems when weighing, pipetting, etc.
