I am 5 months on Enbel. Used auto injector for first 2 months - which failed several times, so dosage wasn't consistent and made switch to sure click. It works way better. Started taking on tuesdays - but with missed dosages was able to move injections to Sunday mornings, to give myself a day of grace for side effects if needed.
HOWEVER- sometimes I would have pain and itching at injection site for a couple days along with the fatigue starting late afternoon - but not always. Nothing super bad though. And seemed to be really hit or miss.
this last week I pulled dose out of frig the evening before, instead of 30-60 minutes before the morning of shot.
Surprisingly I didn't feel the injection at all, didn't get the pain, itching and realize now after reading your post - didn't have the fatigue.
There were times over the past few months I had the doses out of frig longer (we were traveling). So now I wonder if those were my other really good weeks without side effects - when the medicine was truly room temp.
Not sure what your process is but
I'm going to try taking doses out of frig at least 24th hours before for a few weeks and see if that continues to help.
If all else fails - we need to give ourselves some grace when we can. Good luck
