Understandable concerns. I had to get my elderly mother weaned off opioids as she too was heading for zombieville. Yes, she had chronic pain and no possible fix, so pain relief was necessary but well intentioned doctors had upped the dose without thinking that an 88 year old might prefer to be compus mentis! I also
understand that others might have taken a different view, doesn't matter if Mum falls asleep all the time as long as she is not in pain. Blind trust is rarely a good idea, but trust when you get good, informed and honest answers to questions is justified. It was another doctor who spotted my mother's real problem.
