I am going to my fourth of six visits next month and I am beginning to get butterflies. I have never had surgey and the term put to sleep makes me think of putting down animals. Was anyone else nervous about not waking up? I have so much aniexty about the whole thing. I really want to and know I have to have surgery but I am worried about after. I am worried I will overeat or not eat enough. What if I pass out from not eating enough? Any words of advice?
