Trying not to do too Much

I just moved into my new apartment a couple of weeks ago and have boxes to unpack and clothes to put away. But, last week I started on a new medication, Cymbalta, for my pain (back and body) , depression and anxiety and it has made me struggle more with insomnia. I did not get enough sleep for about a week. I usually require 10-12 hours of sleep a night and if I don't get this I battle several infections at once. I got a sinus infection from not sleeping and I also restrained my back from vacuuming for the first time last week (since I herniated a disk in my back last year). I realized that taking the Cymbalta at night, was contributing to my insomnia. So, I decided to start taking it in the morning. Now I am sleeping better but, not anywhere as good as I was sleeping on my last sedating antidepressant (Mirtazapine). I have finally started catching up on my sleep and now my sinus infection is going away and my back strain is also feeling better....so, today I have energy and want to start unpacking. But, I know the dust from the boxes (even if I wear a dust mask) will give me another sinus infection and unpacking will cause more back pain. I also want to do my physical therapy exercises but, I am afraid that it is too soon to do these after the sprain. I think I need to let my SI joints heal and stabilize a little more. And, once this happens, I will take my SI braces off and start exercising and unpacking.
