I think as an employer I would probably accept a proposal like that.

Lets face it - if you are needing to take time off work anyway - it would be easier for them to have it being predictable time (ie every Wednesday) rather than you calling in sick.

Clearly you are not well and it should be obvious to all around you as well.

I think that I would probably speak to the Obs and see what they say and then have a chat with your boss.

Good luck - and hope that the Ms magically disappears soon.
