Medical marijuana in Houston

Has anybody here found a good neurologist registered to prescribe in accordance with the compassionate use law, and especially for Multiple Sclerosis? Thinking I'd like to try it out, but my neurologist is not registered.

How difficult is it to manage what I imagine is a lot of red tape. Is it worth it, in your opinion, vs your experience with more typical pharmaceuticals? What symptom(s) did it relieve most?

Thanks.
