Plegridy - headaches and fatigue

Hello everyone. I have been on Plegridy for 11 months now. I have noticed that fatigue has go worse and now I feel exhausted all of the time. I have also been getting a lot of headaches and for the past 5 weeks these headaches affect me every day, sometimes waking me up at night. I cannot regulate my temperature and go from normal to raging hot many times every day. Has anyone else had a similar experience whilst on Plegridy?

Many thanks
