Attend your local post op support group. they are an invaluable resource for the surgery process. Surgery is only 10 % of the process the other 90% is changing your relationship with food. Are you already logging your food daily? Are you taking your vitamins? Get some samples of different protein drinks. You dont want to stock up because your tastes change after surgery. I like the premier protein 30g premade shakes from sams club. i liked unjury protein powder before surgery but hated it after. have never tried almased. I like vitafusion gummie vitamins, simply right chewable 5000mg biotin, and viactiv calcium with vit d chews, all from sams club. If you have a specific question post it here and you will get good feedback.
my food diary is open feel free to look at what i eat

I hope your surgery went well and I hope you come back soon to tell us all about it. I am scheduled to have surgery September 26th so I'm reading everything I possibly can to prepare. Good luck!! We're thinking about you!!
