Glad you are not having too many side effects Lorraine. I actually found the mastectomy the easiest part - would you believe mine was on my wedding anniversary which is also April fool's day!! Lol!
I am also diabetic - make sure you speak to a doctor who knows about this (I saw an endocrinologist before the surgery to have a good management plan in place. Long anaesthetics (which often a mastectomy is) can play havoc with your blood sugars. High blood sugars create a lovely environment for nasty bugs. Better to make sure you and your doctors have a plan.
I know it may be crazy but I did not even remember the drugs I was on at the time. Kept a list in my handbag.
It becomes a little easier as time goes on.
Do look after yourself.
