hi venik..i answered your other post too..i used to have the exact same problem..too many smokes ,too much tea..the burping would start,the shooting pains in my chest and then the attacks..but i did notice that my depression played a major part in my attacks..i controlled my acidity by taking a 10 day antaacid course..i still smoke as much and drink that much tea..but my depression is under control and so r my attacks.also try and keep your acid levels under control by eating something every 3 hours..it really helped me...hope this helps..please ask me anything else you want to i seem to have got this problem under control for now(touchwood)but i do know how horrible it is..love sanju
