Alan is having alot of memory loss. He wakes up unsure of where we are, he doesn't know where the bathroom is. He reverts back almost 30 years sometimes. He asked me this morning what mess hall We were to eat in. I don;t think he really knew who I was but as he woke up with me in his bed I must belong there. We've been married almost 28 years. Is this a normal reaction to the med's? He is getting 12 mg slow acting every 12 hours and about another 16 mg over 16 hrs of the fast acting for breakthrough pain.
