I'm trying to quit smoking, so I decided to buy one. Truth is that I'm making good progress, but also many people / websites say that they are even more harmful than real cigarettes. I've experienced heart aches while smoking, even though I have heart problems, they didn't occur that much when I was smoking usual cigarettes. I think that could also be because of the accelerated heartbeat someone gets while smoking something. What your opinion on this? Have electronic cigarettes worked for you?
