Yes, I had the same issues with flagyl in IV form. It would wake me up and I would "taste" it and get totally naseoaus. They had to discontinue it, because they figured out it was absolutely killing my ability to eat anything. The TPN doctors kept coming in and saying even though you are on TPN you still have to eat. And I just couldn't. Well finally one of the colorectal docs pulled the flagyl iv... and sure enough I could look at food again.
