To all pre -op people TRUST ME BUY THE ONE PILL THAT KEEPS U FROM BEING NAUSEA ITS LIKE 110$ MOST INSURANCE WONT PAY FOR IT TRUST ME ITS SO WORTH BUYING IT !!! I never got sick once the only time I throw up or spit up is when I eat to much soup or drink too much it's better to spit it up then feel full cause ur stomach can open so I've heard I'm sure it's not easy to open ur stomach after surgery but better to be careful. You have to learn how to eat and drink different . My old habits on how I drink and eat come and go u have to think before u gulp I catch myself doing that because for years that's how we ate and drank so it's a new way of life . I'm so happy I did it tho except the day after I woke up from surgery it's painfull but it goes away after a few hours the more you farting and burping the better u will feel .. SO BUY THE PILL TRUST ME U WONT REGRET IT ...BORROW THE DAMM MONEY IF U HAVE TO LOL GOOD LUCK ALL NEWBEES GOD BLESS
