You might want to do a bit more research on the timing
of taking this injection It takes a few hours for the
side effects to hit and by doing your injection just before bedtime the timing is you are feeling flu-like as you are waking in the morning.
As I understand it, if you adjust the timing and do it several hours before bed, the flu-like symptoms occur more while you are asleep.
There is good information on the page for Rebif, which is another interferon like betaseron -
