MSKPCK, you've reached the BIG decision point. Since it's been 12 hours, I suppose it's too late to give advice now.
My wife has late stage ALS, and is, herself, a medical doctor. She wants NO trach, no PEG, just morphine.
She calls pneumonia the old man's friend, because it's the thing that finally takes them out of their suffering.
Good luck. I'll put more in the forum thread for everyone to read.
