@luna69, Thanks for letting me know that your are feeling more comfortable. I was hoping that you would be feeling better after resting and recovering from the long flight and car ride.
It sounds like your dad is making progress. Tell him that he should listen to his body and to get enough rest. He will continue to gain strength and energy as his body adjusts to the new medications and as he slowly increases his activities.
I wish that I could send you a cooling breeze! But is is hot and humid where I am in the central US.
