First of all, Pat, I would agree that to stay in one's PJ'S all day while working is not very wise. Not because it would "destroy your life", but your jammies! Worn 24/7, your PJ's would be reduced to shreds.
What I do find troubling is the fact that you all of a sudden "realized" that you were still in your PJ's.
It is quite possible that these blackouts that you are experiencing are a symptom of something much greater. My recommendation is to have your head examined.
