Time off work
I took 6 weeks because thats what my short term disability allowed. I am SOOO glad I did. I have a desk job and probably could have come back at 3 weeks but that last 3 weeks was a start for getting a schedule. I had 3 weeks to figure out when/how I was going to eat and when I was going to walk or workout and still could take a nap in the middle of the day. I started working out at 4:30 - 5:30 knowing I couls sustain that after I went to work. I also did a lot of prep cooking and freezing of thinks like chili, chicken taco stuff (the inside stuff no taco) and things like that. Its been great for days I didnt have something from dinner before to take to lunch cause I could just grab and go. I say if you can afford it or you have Short Term Disability try to take off at least 3 weeks. You will most likely feel up to it (minus needing a nap) at the end of 2 but that last week is when you do some good healing and start to feel a little more normal.
Please note - these are only what I saw for me. Everyone is different some people felt great at 1 week some don't feel good for awhile.
