You need to calm down about all this. The PEG procedure is a no big deal.... There are several levels of anesthesia, just because you are not going to be deeply sedated, doesn't mean that you are going to feel pain, or for that matter even remember anything about the procedure. Perhaps you should call your doctors and ask for some premed anti-anxiety pill like diasepam etc. that you can take orally to tone things down some in your mind.
