Like chemo it is impossible to guess how someone else will react. I felt tremendous fatigue, but I had just experienced 4 months of chemo and a double mastectomy. I am uncertain how much these factors impacted my fatigue.

The biggest thing that I noticed is that I lacked reserve energy. In the past I had barreled through any tiredness or exhaustion. However, during and after radiation the consequences for pushing these boundaries, was tremendous.

My advice... If you know a day will be long, then modify the structure to allow time to take a few cat naps. Don't schedule two hard days back to back. Allow yourself the freedom to cancel appointments if you're too tired.

I worked 1/2 time.

It would appear that everyone's comments are pretty much related. The first two or three weeks I had no issue with fatigue. My treatment was early in the morning (8:30am) and I was back home by 10:30am, on the fourth week I found that I was good till about 2pm, and then I just fell apart. I worked during my treatment but I had the luxury of moving my schedule around to soot my energy level, so I would do my work very early in the morning or sometimes if I couldn't sleep I would get up and do it. I never had to deal with clients, patients or the general public so i could do my work no matter how bad I looked or felt. After I finished my TX the fatigue continued for about a month, and the pain hung on for 3 months now (oral cancer of the floor of the mouth). Good luck to you and just try to take some time off for yourself. You can't help your patients if your'e giving them bad advice and if your suffering fatigue and can't imagine that your brain is working all that well. P.S. I used to be a psychotherapist too. Keith

My first radiation treatment 24 years ago, was no problem, I could barely tell I was getting treated, I worked right through, compared to chemo, I would take 2 radiation for one chemo if I had to. But this time, the radiation kicked my butt. Maybe because I was older, I had no chemo this time, just radiation, and the doc said it was the same strength as before. But within one week I could tell the side effects were coming, about 2 weeks in things were changing, at three weeks I could work until about 2 then had to go home for a nap. I could have worked on some more, but at the time I didn't have to so I went home.
Best of luck to you, we wish you the best!
