just today it popped up on my tongue. They say its because they pump so many antibiotics into our system while in the hosp. I don't know, but it's yucky.. Hopefully a good RX rinse will clear thi up!
Can you have low cal/ low fat yogurt on your post op diet? If so, I would start having one or two a day. I mix in unflavored protein in mine so that I still get my protein in.
