It will get better! I'm 4days post op what I had for my 2 week diet was optifast liquid diet and one solid meal at lunch which I had slot of salmon chicken or tuna meat and veggies or salad. I struggled to start off as well but your changing your life for the better it will be easier I promise. I also experienced the hunger and headaches do what you need to do for those I had no breathing problems when I woke up either. Sent from my A1601 using BariatricPal mobile app
