myoclonus and tramadol

I noticed I was having vivid dreams: normal in type but more intense. That's fine by me. I also noticed that my limbs and head and toso were engaged in the action of the dreams, sometimes very strong and disruptive. Over the last couple days these jerks have become excessively strong and frequent, several times an hour and hard enough to hurt, But only when my eyes are closed.

Yesterday I took 400mg. This is the  normal limit. The papers I have read suggest problems  at levels above 600mg. But it is just like me to be sensitive to the conservative pain medicine.I already can't use the heavy opioids, So I'll be cutting back my consumption a lot and hoping for the best.
