Each one is different with how WG affects him and how long it takes to get into remission. Working also depends on the kind of work.
After my WG onset I couldnt work at all for many months. I tried to be back to where I worked but it was too many hours so I quitted. I now work in my own office about 20 hours a week. Hardly enough to make a living but even those hours are not easy for me.
