Hi @jamavon I am also a Primary teacher and had 4 weeks radiation in October. I worked the whole way through and had all my radiation appointments scheduled for after 4.30pm. However, I did have to meet with the Dr two times throughout and those appointments were in the morning so I just took those days off. I didn't notice the tiredness during treatment but felt exhausted by the end and in the weeks following. During November I took a handful of days off work to rest. I'm now 2 months post radiation and finally feeling like I have my energy back!! Best of luck xx
