Hoping someone can help. I have had my ecig now for about 3 weeks. For the first week I was so pleased, couldn't believe all the reviews I read were so correct. Then I had trouble trying to breath, didn't feel as though I could get enough air into my lungs. Like a few others on some other posts I too started getting chest pain. Very much like the worst sort of reflux you can imagine. So I took all the right medications etc for that, no eating acidic foods etc etc. Waited for a few days until the pain had gone and breathing was back to normal before trying again to see if it might be the ecig. Started using it again today very moderately, but all the symptoms are back again. Not saying they are good or bad things, maybe it is an allergy to one of the ingredients. Wondering if anyone else has had the same problem.
