Hello. Newbie recovering from gastric bypass advice

[June826]

Hello. I started my weight loss journey recently and made it through the pre surgery diet. It was hard sometimes, but I was determinedto do well and lost 8 pounds! I just had Gastric Bypass with a hiatal hernia repair yesterday. I am home and having some pain and a little nausea. I am finding it hard to get my fluids in. I feel full quickly and don't want to drink too much at a time and mess up my surgery. I am glad the surgery is over, but scared I will drink too much at a time. I feel no hunger at all. How long will my abdomen hurt? I hope this journey will be worth it.
