hello, create a food diary.  this will give you an idea of what foods triggers your symptoms. try not to lay flat on your back or tummy.    this will allow stomach acid to travel through your esophagus.  drink more water during the day.  chewing gum helps to create saliva which helps minimizes stomach acid.    it's usually said eat three to four hrs. before going to bed.  but for some [like myself] that may not work.  so try to eat five or maybe six hrs. before going to bed.   as good as nexium is you can also experience quite a few side effects.  talk with your dr. about taking prilosec which is just as good as nexium, but without all of those side effects.    try to lose 10lbs.  being overweight even just a tad, can relax your lower esophageal sphincter.  this valve is what is supposed to keep stomach acid in the stomach.  when it's relaxed, the acid will travel through your esophagus and heartburn will occur.   i hope this helps.    samuel www.acid-reflux-tips.com
