I've been using PM for 2 months so far and haven't experienced any. Though I generally experience them when I am exhausted or have had too little sleep. Perhaps this is the reason for yours?

I'm at almost 2 years on PM (except for a few breaks). I started noticing the twitching about a year ago. For the longest time I assumed they were due to a back injury but I now know that's highly unlikely.

Mine are very frequent and last for hours at a time. They're definitely not due to exertion or exhaustion, but thanks for the input!
