I am new here and scheduled for surgery 9/20/2022 just a few days away. I've been on the modified preop diet with two meals and two protein shakes. I feel okay, a little sluggish because of no caffein, a little scared, very excited to lose weight, hoping for the best outcome. I wonder if I will be able to sip 64 oz of water per day. I calculated one sip every fifteen minutes. I hope that I can stick to this schedule. I am easily distracted and may forget to take a sip. I am so used to taking big drinks. I don't have any problems staying hydrated now, but I can swallow a lot of water at once. The small sips will be something to get used to.
