Hi Everyone, I was on Copaxone for 15 years and had very few issues at all. I decided to switch to Gilenya recently since my body was just tired of the injections and I heard such good things about the Orals. I started Gilenya 1 month ago. All was well for the first couple weeks but I am suddenly suffering from fairly serious fatigue. I'm very health conscious.. I run quite a bit, and have never had any fatigue issues due to my MS. The last 2 weeks I've really struggled with just running out of energy. I feel winded when I just go up and down the steps. My runs are very uncomfortable and I feel much more worn down. Anyone else have these issues.. did they pass over time? Not sure how long I'm willing to stay with this. Any input is appreciated. Thanks! Bill
