I seeking information from those who are now, or who have taken primidone/Mysoline for tremor. 1. How long did you take it? 2. What difficulties did you have in taking it?(side effects) 3. If you have discontinued it, what made you quit? 4. How long did you take it before its lack of effectiveness started? 5. Were the sedation effects/sleepiness overcame while on the drug? 6. What was your dosage when you quit or now taking? I have tried it twice, but that was 6 years ago and I am unable to remember the details. Perhaps your answers will fill in the pieces of my spotty memory.
