I arranged three weeks off - one week for hospital (which was really four days), and then 2 weeks at home.
I knew I'd feel fine after a few days, and as I have an office job I could go back, but I felt I needed the two weeks to get used to my new life, my new eating regimen and I'd like to be sure i can stomach solids before i return to work.
If I PB at home it'll suck, but at least I have the comfort of my own bathroom. At work it would not only be painful but incredibly embarassing, especially since I've not told a sole at work what I'm doing. As far as they're concerned I'm having an operation to do with my sleep aponea (which is technically correct), so sudden 'vomiting' and constant belching through the office would seem very out of place and completely unprofessional.
