I'm glad you feel well after the treatment. As far as re-treatment goes I believe after the second infusion they will respond based upon need. If you show no signs of disease activity there is no need to retreat with what is let's face it, a pretty serious drug.
I gues us old timers don't visit that often because we have made our decision and are busily getting on with life. MS to me is a minor irritant that will not go away but also shows no sign of getting worse.
I am glad that I made the decision that I did and really hope that you and any others who decide to try Campath get the results that I have had.
Do not go gentle into that good night. Rage, rage against the dying of the light.
