Phew - we are home and all of the tests they ran showed nothing! Except for sinus issues, which we knew about. They really had no explanation other than over-exertion and dehydration - and a bad case of sleep apnea because of those 3 factors. He's been working 12 hour days since July ... and works 11P to 7A (or when on OT 11P to 11A) and gets very little sleep during the day. He will be 57 next month and I seriously think it's his body telling him to SLOW DOWN! (works @ the local tire manufacturing plant, making big rear tractor tires - it tough work - but his has nice big muscles because of it

). Unfortunately most of the OT is mandatory, however; I think this gave him a wake up call - so I hope he slows down and tries to get more sleep when he's home (he's a giver - always wanting to do things for others, not always taking care of himself). Thankful it is nothing serious - but it was pretty stressful!! Now - time to take a hot bath and go to bed ...!! Thanks again for the kind words and prayers!!!
