It seems fairly common to shake more when one is feeling the cold. I have this problem mainly in the winter months in spite of wrapping up warm before leaving the house. Shaking is increased in any stress situation even when I am speaking to my Neuro my symptoms become worse; though I know that he is there to help me. I see him every two months or so. He has at last given up trying the newer drugs on me. I now stay with my Sinemet and hope to keep warm this coming winter. Bern............Peace. http://members.teleweb.at/bernard.shaw/poetry.html
