Hi TiredArtist
Yes, I have experiencing muscle spasms, like butterflies, in arm muscles from day one. I also get shaking and, thankfully only occasionally instead of weekly, my hand just drops it's grip!
I am sorry about your pain :(
My experience is what you already hinted at, don't keep using it while the muscles are spasming. My arms calm down based on time in use and how intensely used.
Blessings
