No one ever really spoke of pain when I was researching information before my surgery. All I heard was that everyone loved their sleeve, and they were back to work in a few days, and even some were shopping right after surgery...so I was hit HARD after my surgery. I couldn't drink, eat, woke up in PAIN, constipation, the sliming issue, it was a rude awakening for me.
I really think if you expect the worse, it's better. At least you will be prepared.
Hoping you feel better soon
