Hi Daffodil,
I agree with glenc that the effects vary so much from one person to another.
Background: I do office style work from home (and have done for years before my diagnosis).
When I was diagnosed, I went on sick leave, but it was partly a matter of mental health after getting such a life changing, traumatic shock.
By the way, I had the same treatment as glenc (which is pretty standard) except that I had lenalidomide instead of thalidomide. I didn’t have an STC.
When the GP asked me how long the sick leave certificate should be for, I picked four months out of thin air. After that, I came back gradually to work.
However, working full time again proved impossible due to fatigue, so I took a few hours off here, a day off there. It was a messy set up both for my employer and for me. They never knew when I would be well enough to work, I would push myself to work hard even when I wasn’t really up to it. After a year of that (in remission), I arranged with HR to go part time, with my work spread over the week.
I call it semi-retirement. I have more time to enjoy myself, and no guilty conscience. Meanwhile my employer – which has bent over backwards to support me – knows where it stands.
Regards
Rabbit
