I haven't had any vivid dreams!

Are they interesting ones?
I am on tizanidine (generic Zanaflex)
I just sleep like a log! That for me, is a good thing, since the spasms used to wake me up all the time! I also take Baclofen for spasticity, maybe that would help you.
I'd say let your neuro know what is happening and see what he has to say. He may have other alternatives for you.
Good Luck!
