I don't know if you know this or not but if you're having trouble with your vitamins you can get them in patch form. I don't use them but I here they work very well. As for the rest.... don't stress it'll all come together in due time. Before surgery I hardly ever drank Water. After surgery I still hardly drink water and in doing fine. I was sleeved on 9/7/16 and I've lost 50lbs. Some might say that's slow but I'm fine with that. Sent from my SM-N920T using the BariatricPal App
