Stomach, Digestive, Intestinal Problems Questions

I have always had a problem when it comes to my gag reflex. As a kid I even had a problem wearing a mouth piece and going to the dentist. but it still has not gone away, even today if i go to the dentist it is very hard for me to allow anything in my mouth without gagging and eventually vomiting. I also have a problem when shirts are tight around my neck. Is there any hope in acupuncture?
