Gilenya
"I have been taking gilenya for the past six years. It has been the only medicine I have been on for Ms. I thought it was a great option for the first few years with very few side affects and only one relapse per year.  Then my hair started thining and the headaches and fatigue got really bad.   Now it no longer seems to be working. Last  mri showed several new lesions  and my Dr said the drug is doing little to nothing for me. He wants me to switch to Tysabri but hearing the risks for that terrifies me."
