Done With One!

My first radiation treatment went well and other than having to stay in one position for 25-30 minutes, it was a piece of cake.  I knew they were doing x-rays first but I didn't know they were also doing the radiation.  I kept asking if I was done since it seemed like an awful lot of x-raying going on.  She came in the room and helped me off the table and said I could get dressed.  I said "you can do the radiation with my clothes on?"   She laughed and said I was completely done.  Never remember her saying both things were done in the same room with the same machine but, I'm sure she did.  Can I still blame not remembering on chemo brain?
