Karen - thank you so much for your detailed reply. It has been extremely helpful to hear how you've done it. The onc suggested similar, so to hear that it's possible is great.
I love my work, and like you, would go crazy doing nothing the whole time! They are great too, and fexibility won't be a problem which is so reassuring.
I have to speak to the boss about it all tomorrow, so that will be another weight off my shoulders to know that it's all locked in.
Thanks again and good luck with the rest of your treatments. :)
