All the best for a smooth recovery. Surviving twelve hours of travel just after surgery may be an indication that you'll be a quick healer. But as everyone has said, take it easy.
Hey Gary - welcome to the other side!! Wow - 12 hours travel... I just did a 3 hour trip and that was enough for me! Take it easy and give yourself plenty of rest.
There's no place like home!!! Hope your recovery is smooth sailing from here on out. 12 hours is a long trip mine was only 4 hours, and I was ready to rest when I got home. Eat, Walk & Rest and keep us posted.
Welcome home Gary & I hope that your recovery goes well! The biggest hurdle is over; now you just have to take it easy on yourself & allow yourself to heal!
