In terms of MS therapies out there--instead of Copaxone, interferons, LDN, Tysabri, and Estriol, how about Minocycline? I've been doing a lot of research about this tetracycline antibiotic today. It's cheap, appears to have anti-inflammatory and immune-modulating properties and is in clinical trials right now for MS. Just google Minocycline and Multiple Sclerosis and a lot will come up. Here is one of many:

I've been on it for acne for a year now. I have had no progression. Granted I am also on Tysabri but now the neuro thinks it might not be safe to be on Minocycline and Tysabri together. So I have to go off the Minocycline. I can't tolerate any other MS drugs and if for some reason Tysabri no longer works I will go back to the Minocycline on full dose until the new pills come out. It is very very easy to tolerate.
