Vitamins - VSG
Your doctor's office my sell most of what you need. Mine did. Do what ever they say, and you'll be just fine.
I'm only one month out. I take 2 multi vitamins with breakfast, calcium bite at lunch, and another 2 hours later, then my last calcium at dinner, and a multi vitamin at bedtime. My multi vitamins are huge but I haven't had any trouble getting them down. I also take 5000 mg Biotin each morning.
Best of luck!
