Hi Kitty. Tec hasn't slowed me down at all, been on it 5? months now. Only complaint is if I have one nightly alcohol drink I get warm. Good for winter heh.
Tec is darn close to Tysabri for effectiveness i'll say but i'm going back on Ty next month likely. I miss my chemo friends & nurses no seriously..I want to see if Ty works as it did in beginning, since i've gone w/o it for a while now.

I swam 3300+ laps in a 28' long pool so far this yr. Doesn't slow me down.
