Excessive phlegm production while trying to eat

I am a non-smoking health professional that thought I could treat or find someone to treat just about any ailment possible. I lean more toward naturopathic modalities of healing. But I have become desperate.
I feel like I have the most bizarre eating disorder "never" heard of. I've had a barium swallow and endoscopy performed. Every test proved normal function and no cancer,polyps,ulcerations or obstruction . My issue is that it seems my brain does not connect with my esophagus when it comes time to swallow chewed food. Sometimes I can swallow pretty easily other times I have to spit the food out or I feel I will choke on it. When I am able to swallow, there is so much phlegm production that I actually have to stand by a sink to spit it out every time I have swallowed. I feel it has to be coming via lung production because of the feeling of breathing thru bubbles best describes what happens. This has been going on since May 2007. There was a 3 - 4 month period where the whole issue "totally disappeared" and I could eat normally. But it returned without warning. I figured it had to be psychological in nature then, and went to a hypnotherapist for 5 or 6 treatments. Still no alleviation of symptoms. Suggestions???

It sounds like GERD (acid reflux).  The bubbles may be the acid backing up in your throat and most people with GERD will feel like they can't swallow or are choking. But your endoscopy would have shown this.  If you feel it's psychological then seeing a therapist would help a lot and you may need something to help with anxiety as this would be causing you to feel like you can't swallow.  I hope this helps, I know it's very scary to not be able to swallow. I wish you all the best and take care!
