I was banded 4 years ago and have that same problem. When I go to bed, exactly 1/2 hour later I get this awful tickle in my throat that won't go away until I get up and "get rid" of any mucas or lingering food. Then I am able to go back to sleep without any problem. I have pain sometimes too, depending on how hard I cough. I talked to my doctor and he either has never heard of it or didn't seem to care. Just told me not to eat close to bed time. However, that's never been a problem - I don't eat close to bedtime. So the long and short of it is that I don't know what to tell you - but you're not alone.
