Make sure you inform your Docs and they can ensure that you the right things in your IV, especially if you have low sugar.
You'll be able to pretty much eat whatever you can tolerate and are ready for. Once you wake up, they will take it slow in order to make sure you don't over do it.
The only "issue" some have is depending on the type and complexity of your surgery, some blood my go down the back of your throat and into your stomach, which could make your a bit upset upon waking. The stomach doesn't digest blood very well, so sometimes, one may even throw up, but it's minor in nature.
Best of luck to you.
