I am sorry that they didn't find much to help you. I can tell you that depression cannot be causing all of these symptoms. I can't imagine your frustration right now. Mark has a hiatal hernia but doesn't do much for it. I believe it causes him to have problems breathing and if he eats too much can't sleep real well at night. When all of his scary stuff was going on back in May they found nothing wrong but he still has problems breathing. I believe his is more stres induced but not yours.
As for the sleepy juice yeah that happened to me during my colonoscopy. I remember them sticking that thing in my butt and me yelling out "that really hurts!" The doctor said you can't be feeling that and I said "Oh yes I am!" I must have eventually passed out from pain or they really upped my medication because right before they wheeled me out I was unconsciuos. Vercet did nothing for me!!!
I keep you in my prayers and hope that you get some answers. Love ya!
