Multiple Sclerosis
"Tysabri has changed my life. I have had 20 infusions now. At first I could feel a major &quot;up&quot; and then could slowly feel the medicine wearing off towards the end of the 28-day cycle. Now I don&#039;t feel much of an up or a down, but I feel consistent and &quot;normal&quot; again. I feel more level-headed, have consistent energy levels, and am able to work out at the gym two hours a day! The only side effect I&#039;ve ever had was a bad headache on the evening of my infusion for the first 2 or 3 months. At my 6-month MRI/follow-up we found out that the Tysabri was actually causing a significant reduction in my lesions. I haven&#039;t had a relapse and only a handful of flare-ups (that last maybe an hour tops)."
