I had the sleeve surgery Monday (9/18) and was discharged on Tuesday. From Sat 9/16 until now, I have lost 20 lbs. for me, the hardest part is that I have a high pain threshold it can be difficult to determine when to take a med for pain. I am starting to figure it out. The second issue is forgetting to take small sips. Once in a while, I do a little larger swallow and my stomach reminds me.
