Frank, I'm doing pretty well also. I wish I got on better with swimming, though, because I know how good it is for you. Luckily, though, I got over feeling frightened of what may happen next month about three years ago. I'm more frightened of swimming.
Taking abx for a year before restarting tysabri might have done you more good than you realise, if you have had no relapses in that time, then improvements will happen in their own time. I am still getting subtle improvements now, well over a year since completing abx.
An Itinerary in Light and Shadow Completed Dr Charles Stratton / Dr David Wheldon abx regime for aggressive secondary progressive MS in June 2007, after four years. Still improving with no relapses since starting. Can't run but can paint all day.
