Anybody have a positive experience with baclafen for spasticity?

I have thoracic myelopathy causing foot drop and spasticity in lower extremities. My doctor recommended baclafen for these symptoms.
Has anyone experienced success with this drug for spasticity? Any side effects to be concerned about? Recommended 5mg once daily for one week, gradually increasing dosage and frequency as needed. Any feedback regarding use of baclafen would be greatly appreciated.
