Hi...I read everyone's comments...very helpful. But my morning vomit has no pre-nausea feeling. I have a lot of post nasal /tons of tears running down my face...try to walk it off...then boom. With no warning I puke. Usually 3-10x. Nothing comes out but a bit of clear fluid...as I have nothing in my stomach from night before. Once I throw up...I feel better (though shaky & exhausted from the episode)...tears go away ...runny nose stops immediately...and gag reflex all gone like magic. My dad had this as well every morning. The post from someone who lives in WA about his father having his root canal to unblock his sinuses makes sense as I still have all of my wisdom teeth as did my dad! Doctors have never considered this!! And also I too have a craving for cold fizzy drinks vs coffee in the morning. I'll try the lemonade. But as everyone knows...fluids are the last thing you want. Especially when you feel as if your esophagus & upper GI are drowning in fluid.  Wow. Mahalo to everyone & I hope everyone finds a solution because it's a horrible condition and not a great way to start your day.
