I was on copaxone and switched to Tysabri. It took a lot for me to decide because I’m in a certain part of my life where I want children and I also still want to work and so forth. Copaxone wasn’t giving me the full effect of having a fulfilling life. I was struggling to walk, having terrible fatigue, brain fog, and being in a crowded place was truly difficult for me to focus and function. I can definitely feel a change in those specific areas since I switched. I still have many symptoms but definitely more tolerable than before.
