If it was anybody but Dr. Wynn I might. I was on Rebif for about five months and had a bad reaction. I doubted my treatment then and he put me on Copaxone.
Of course we have doubts, since this disease can be so variable. But Dr Wynn is one of the top in the country in his field. I know I'm in good hands with him.
If you change your mind about the trial, let him know though. You aren't obligated to do that at all.
Alternative treatments have no known records for success though, other than the opinions of those who have taken them and that hasn't been scientifically tested, it's just word of mouth.
