Primidone
"Have had essential temors for many years, now at age 69 they interfered with my quality of life.  Could not hold anything steady and my beautiful penmanship was horrid!  I fought the thought of taking a prescribed medicine since I was so lucky not to take any, even at my age, except Imitrex for migraines 2-3 times a month.  I am taking 50mg 2x a day, and it has been working great, even the migraines has decreased.  I am sleeping so soundly at night that my days are so much better.  After 4 months on it, I have noticed no side effects, but a little of the tremor is returning, which my doctor told me could happen.  Not ready to increase dose though."
