Have you tried taking an over the counter acid reducer for a few weeks and see if it improves? I don't often have acid reflux but if I do, it's 2 to 3 a.m. when it bothers me.
It would be a cheap, easy thing to try. Take the pill about 30 minutes before you go to bed and see if it lets us.
If you already take one, this I've been of no help what so ever. : )
