I have suffered from GORD or Reflux just over 2 years, regularly take 2 tablets a day for it, in all honesty smoking full stop irritates it, i have found since starting to Vape last Friday it's improved, admittedly i am also going through the normal withdrawal symptoms lol, can i recommend buying Lemon Ginger herbal tea adding a dash of honey, it settles heartburn big time, or go get some Omeprazol from your doc ;-)
other tips carbonated drinks and coffee, certain citrus drinks and spices along with onions and tomatoes also make it worse, if you suffer badly try to moderate or avoid the above...
