Gastric sleeve Rad-Girl

Hi Everyone... So i am only one week post op with a robotic gastric sleeve. I am feeling so much bloating, gas and a little pain. It's hard to tell if its pain or hunger. I have only loss 8lbs so far is that normal or should i have lost more??? I see people post they lost 20 or 30 and i think am i doing something wrong? I do well with getting in the 60g of protein but not sure if i am getting in enough water. The struggle is real.
