Fascinating. I'm on Tysabri, and regardless, steadily sliding down the hill. While my intuition tells me this is poison and doing more harm than good, I'm scared to get off it. My Neuro says, "yes, but you could have been worse off without the drug". A perfect example of a ‘not scientifically proven’ claim. The same could be said for eating an apple a day. And yet, there is this little voice in my head that keeps on saying; "and what if she’s right"?
