SA,
I've just completed 25 yrs in the Airlines on heavy metal and would strongly suggest you wake up and smell the roses. Airlines used to be good but these days its just max duty min rest, limited days off and lots of long haul night flights. In marked contrast I'm now flying a Gulfstream, VIP flying is a breath of fresh air. VVV few night flights, vvv low hours and varied destinations. In short it has revitalised my enjoyment of flying beyond all recognition. I now look forward to going to work, especially with the benefit of a few days off and a good nights sleep or three. Best of luck whichever way you go......
