Hi m8, I'm going to make a quick post because i'm at work at the moment...
I can say that I suffered from this problem for a large portion of my life, up until I was about 22 or so ( this is when I had my first of 3 operations to widen my oesphagus ). I felt really depressed and it ruined any social aspect of going out to eat with family and friends. I know the feeling especially when people are sitting across from the table and you're having difficulty swallowing and they are looking at you...
I can really relate to your problem and it's very rare that I come across somebody who has, or had the same problem. You won't believe the confidence and other improvements to your life when you have this fixed. It turned my life around.
I wish you well and goodluck.
