My husband completed 20 sessions of radiotherapy for prostate cancer in March 24. The treatment was successful but although he has returned to work he is constantly needing to sleep when at home, . He was formerly very active but now can sleep for hours at a time during the day when he is not at work. He sleeps 8 plus hours at night then wakes only to fall back to sleep. His libido has not returned since the hormone injections were given to him before his radiotherapy commenced. He would like his previous energy levels to return.
