yes, this is true. I usually have a lot of side effects from drugs, and in fact had to go off copaxone because it made me too sick. But I have virtually no side effects from my tysabri infusions - i'm a bit woozy afterwards (in part because they give me benadryl right before the infusion) for a day or two, and sometimes a little digestive weirdness for a few days but often not. And that's it.

To me, the scariest parts are that it is strongly immunosuppressive and you are more likely to get infections - for example I've had several UTIs since starting 8-9 months ago - AND there's the possibility (which increases a lot around 2 years of treatment) of a very bad disease called PML. So I'm hoping to get off after about a year .
