Hi and welcome! I am about 5 months out from my surgery. That's great you are meeting your daily water and protein goals! Be sure to get a lot of rest and if you can muster the energy, walk around your residence and around the block each day. I did have a time where I went to the local pharmacy and felt very dizzy. Your medical team will be happy if you check in with them about any medical questions that pop up. I also had a hiatal hernia, and I'm 50, and recovery took me a while. I had very little energy but I would force myself to go out for a walk and then rest the remainder of the day. You are only 1 week out, please do take it easy and it will get a little easier as each week passes.
