Mine was Lap also...and I was more tired then normal for the first few days. The biggest thing is getting enough water, enough protein shakes down, getting all that to stay down and, for me, getting enough salt. My dr's nurse was good enough to tell me to drink salted bullion between "meals" as some of my fluids. It really was very helpful! Especially with the feeling of being tired. When I got the salt, I felt better.
Important to Sip Sip Sip...all day...everyday...water, shakes, bullion or whatever your surgeon or their NUT tells you to Sip.
Keep up the great questions!
