benign essential trem
"50 mg/day.  Helped but after a couple of weeks started to itch in very personal places.  Kept taking because itch was preferable to shakes.
Then developed vertigo and quit taking it.  Vertigo went away.  Resumed because vertigo and itching was preferable to shakes.  Vertigo and itch subsided after 4 weeks. Shakes somewhat better."
