Give yourself as much time as you think you need. Going back too early will only set you back, or so I believe. I am out on disability right now because of a bad flare. Although I am feeling much better than I did, I know that if I went back to my old schedule right now that I would hinder my recovery and possibly end up right back where I started. You know your body best, so just listen to it.
