+1 on change jobs/employer/go remote. If this is not feasible it could be that you 'just' need to change the room/floor/corner of the building. Perhaps move closer to a window. Something facing West will give you natural light after 11am, or East for the early walk-ins. I remember I was working in one of them new skyscrappers in London a few months ago. We were given a meeting room so the whole team can stick together for a massive project. The room's name was "engine room". EVERYONE was sick all the time. The room was cold, with minimal light, and we were pulling 12 hours shifts in there. The £ was great, but we all almost got pneumonia. When that project was finished and we were "free" to wander on other floors (or work remotely), I found a desk right next to the windows and haven't coughed since.
