The only advice I would give is - get to your doctor as soon as possible. The way this disease presented itself when I was first in my doctors office, it was so rare they couldn't give me a straight diagnosis.
At it's very worst, I was at my doctors office everyday - just so desperate to get some help. I was emotionally and physically drained. I'd got to the point that I couldn't even swallow a glass of water without bringing it back up. I'd already lived on mashed potato and gravy for 3 years, it was the only thing I could suck up through a straw!
Seek medical advice immediately and challenge the doctor if they say it's NOT ACHALASIA!
