I'm sorry you're going through a tough time! I've been on Cimzia since last summer and it's worked really well for me, but it doesn't come without some side effects. I get super tired (more tired than usual - I'm always fatigued!) and also nauseous the day after I take my shot. Not sure if the nausea is common but I do think the fatigue is. Ginger tea is a huge help with nausea and I try to take it as easy as I can the day or two after my shot. It's worth it, though, as Cimzia provides me a lot of relief. I hope it does for you too and that you find some ways to cope with the side effects! Best of luck.
