Thanks Jake! I take clonazepam for Exaggerated Sleep Myoclonus-.a reaction to a medication called Reglan. When I found out after all these years that a side effect or tolerance effect of Klonopin was...…. myoclonic jerks, I realized it was time to try weaning off and see if was Klonopin or my body causing the jerking. Glad I did. It's starting to look like the original Myoclonus has resolved after all this time.
