I changed before my dx. It was these changes that sent me to a doc. Before MS, I only took vitamins and exercised almost everyday. I swam, biked, did step aerobics, pilates and lifted weights. Now I am exhausted at the drop of a dime. I can't remember the last time I wore heels or had a cocktail or exercised. I can't stand needles but I take my rebif as directed. It hasn't even been 2 years since dx but it feels like a lifetime. MS has severely impacted my life. I am not the same person I used to be.
