Hi nanny Annie, I to have had breast surgery, not as detailed as yourself. I am also taking letrazole, finding I take things 1 day at a time. Very tired this week 3 weeks after radiotherapy. Luckily groceries get delivered & only have a garden to worry me. I need to get out walk, cycle something to tire me as yes sleep at night not great. Take heart things do improve keep busy if you can. Best wishes.
