We must have the same ill-fitting desk chair.
It sounds like you're doing great, but boy can I relate to the body aches at 2 weeks and the back to work blues. I was hoping to return to work early, too. I thought that I'd go back in two weeks, but right before leaving work something told me, at the last minute, to change it to three weeks. I was glad that I did because I was just too sore and still moving around slow, like a old lady at two weeks. I went back to work this Monday after 3 1/2 weeks and felt pretty good, but sitting for long periods caused some discomfort on my right side. Not enough for meds, just uncomfortable. Today, no pain in my side and feeling almost 100%. Your going to feel so much better in a week. You'll see. I'm talking about the soreness, not the job. ; )
I was sleeved April 18 and I'm not cleared to eat deli meat, yet. Sigh....
Congrats on doing so well.
