I had my gall bladder removed when i was 16. since then i've had pain near there. sometimes when i eat. more in the middle of the night. if i gulp water. & sit up it goes away. its so painful.

Smaller meals: Eat smaller meals more frequently, no food at lear one hour before bed. Do some relaxing physical activities before sleeping...

Plz See GI Doctor: What you are describing sounds more like a problem with your esophagus. This may be as simple as gerd, however there are many other diseases to consider. I suggest you see a gastroenterologist to help sort this out.
