I thought it was very funny that they allowed people to take LDN in the Tysabri trials, but apparently they did. I would have thought that could potentially skew the results.

Cheryl would know better what the protocol is since it's been reintroduced, but I'm not sure why they would have stopped permitting people now. There aren't too many neuro's that take LDN too seriously anyway, so that might contribute to the reasoning.
