Clonazepam
"Started on 0.5 mg at bedtime for possible restless leg syndrome, developed flat affect, lack of emotion, somnolence. Reduced to 0.25 mg at bedtime. Kept on this med by another neurologist who diagnosed tardive dyskinesia. Third neurologist increased to 0.5 mg at bedtime in attempt to promote better sleep (had restless sleep to this point). Found not helpful with sleep, still woke up many times and restless with increased somnolence next day, so decreased back to 0.25 mg. Med was somewhat helpful decreasing uncontrolled movements of TD, but not a lot. While not effective in my case in promoting better sleep, it was somewhat effective in reducing some of the uncontrolled movements of tardive dyskinesia, for which there are few effective meds."
