I returned to work 8 months after completing surgery, radiation and chemotherapy for a stage 4 neck cancer. I am now considering going back on disability as I find myself increasingly fatigued. My job demands travel and when I travel I eat very poorly. I lost 65 pounds during treatment and was at about 125 lbs at completion. I'm now at 141 but lose weight each time I travel. Also, I find that I am not as mentally sharp as I was prior to treatment although I feel that in time, I will be. All in all, it is about energy levels; however, constant sinus infections haven't helped the situation. I am 62 years old.
