HarryM, it is good to read that mirtazapine is helping with your tremor

There is some general clinical evidence for this: http://www.ncbi.nlm.nih.gov/pubmed/23917951

This quote from that link (the emphasis is mine) might help members with PD to discuss the option of mirtazapine with their clinical care teams:

"Other options include 5-HT2A antagonists, and drugs that have mixed binding properties involving serotonin and acetylcholine, such as clozapine and the antidepressant mirtazapine, can be effective in reducing PD tremor ."
