Think you might have hit the nail on the head, Nikki. Could reluctance to prescribe be because it's not approved for this use and could make docs susceptible to liability?
If that's the case though, I'd still love to hear any doc's "thoughts", even if they won't prescribe it!
Last thought -- if it hasn't been medically dismissed in the U.S. as being effective for MS, one can only speculate why research hasn't been supported....
