I definately feel for you. I had anxiety over the idea of having an EDG. It does not sound fun at all. I was pretty lucky in my doctor did not feel the need to have me do any extra tests or studies. Just had to do the insurance required doctor supervised diet (insurance excepted my 5 years of failed Weight Watchers for this requirement) and mental health assessment. Then my doctor's requirement for everyone is the dietition consult, exercise consult, EKG and blood work.
