@bdurel, with everything that you have coming at you right now, I'm not sure how you are managing at all. Give yourself some credit too. You are keeping your schedule together, and are investigating the medications that you've been prescribed. This is a lot!! Please keep letting your cancer center know of your concerns, with the hearing loss and the medications. Let them know when something doesn't seem right, and when you are too tired to move forward.
There may be some cancelled golf dates in your husband's future. 😉 Take a deep breath on that one. I know it's hard to ask for help. You won't be able to do all of this alone. Do you have one family member or a trusted friend who may be able to coordinate rides or sitting with you during these appointments and treatments?
