Deb -
For me, it was more annoying driving around looking for parking and changing in to a gown then it was receiving radiation (the later took less time).
This will be far easier than chemo! I have heard people complain of fatigue but I never experienced it. My appointment was at 7:30am and then I went off to work.
and yes... lotion, lotion, lotion. I used Aquaphor a minimum of 5 times a day. I made sure to keep the area extra moist to avoid any blistering.
I had my last radiation treatment June 6th of this year, and to look at my breast it only looks at though I have a slight tan.
Good luck - you'll do fine
