Does anyone know if Flexeril aka Cyclobenzaprine effects the heart? Or maybe I should say does it effect the heart very much, because I'm sure it does a little.

I'm concerned with raising or lowering Blood Pressure? It might be good if it tends to lower it, but it would be bad if it raises it. My doc gave it to me for leg cramps at night, but he gave me enough to take it in the day too, if I needed it.

I'm hoping it might help with RLS. And I think I'm getting RLS from excessive anxiety. The doc I have right now is alright, but he doesn't want to treat me for my chronic anxiety which is very bad right now due to forces that are out of my control.
