I've seen it take longer. You just have to be patient. Get lots of rest, eat well and do the best you can at work. It will gradually improve.

Anesthesia can be really tricky for us. I had an exploratory laparoscopic surgery of my pelvis a while back and they were so careful to jump through all the MAOI hoops. I did great with those things and yet developed akathesia so bad I landed IP to stop it a month or 6 weeks out. Not saying you'll wind up IP, that had a bunch of factors (mainly the MAOI) at play, but just be gentle with yourself and it will improve.
