Ritalin and "jumps/jerks"?

[Sinopa2]

Hi! I have a general methylphenidate question - has anyone out there experienced twitching (myoclonus) from taking this drug? It feels kind of like an electric shock, making your fingers/leg/whole body/whatever jump without your control. I think jumps like this are pretty common right as people are falling asleep. Anyway! Has anyone experienced excessive daytime "jumps" as a result of ritalin?

I really appreciate any input!
