my partner is on 30mg x 3times a day after having treatment for throat cancer, he is so tired and can sleep nearly all day, is this a common side effect? his doctor advised to cut the middle tablet out at lunchtime but he felt so sick he started taking it again. He had chemotherapy for 6weeks and radium treatment for 7 weeks. His treatment finished 12 weeks ago and is fed via a peg feed in the night. He had his PET scan 2 weeks ago and has been given the results that we were hoping and praying for, the all clear from throat cancer.
