This is major surgery and the normal post surgery conditions will apply. Gas, sore throat, incision pain and stomach distress. I was very fatigued for several weeks as a result of the surgery and decreased caloric intake. Many people refuse pain medication but not me. I took it as directed and stayed agead of the pain and experienced very little discomfort. Your stomach will be very swollen for several weeks and uncomfortable. Sip very very slowly and wait between sips. You may feel some pain in your chest when you drink. Wait for it to pass. I found warm chicken broth the easiest to tolerate that first week. I did not stress out about meeting the fluid and protein requirements and just did the best I could. Three months out I still don't meet the recommended fluids but get close. The first week I was hormonal and doubted my decision but that passed in several days. I'm not going to lie. The 1st month is tough. Three months out I am 52 lbs down and feel great. A stall will happen but stay on course bc it will pass. It is all normal. The weight will not magically fall off 48 hrs after surgery. At this point I lose about half a lb daily and weigh twice a week. I am 67 yrs old and this surgery will extend my life. That was my purpose. Relax and just ride it out. The journey is worth it. Best of luck.
