Hi there i am a 30 year female who didn't smoke. i started using the ecig with 0 mg of nicotine. i always noticed my heart got faster when i smoked. i used a small amount of nicotine sometimes i would mix 0 mg with 6 mg of nicotine. 3 months later one day at my friends house while sitting down after dinner my heart started beating sooo fast. it was really freaking me out. my head just felt soo weird with heart palpitations and my chest was tight and i thought i was having a heart attack. i went to the ER. they took Xrays they did blood test. and they found nothing wrong and sent me home saying it was a bad panic attack. i started thinking well maybe i shouldn't do any nicotine. so i upped my pg levels with no nicotine and then i had more heart palpitations. So i was looking up allergies to Pg and it seemed like i was allergic to it. so i quit it all together. everyday my heart feels like its beating so fast and hard for no reason and then go away. i had really bad stomach acid too. i also read that pg if smoked too much can turn into lactic acid in your body and too much lactic acid can also cause anxiety. one night i threw up from so much acid in my belly. that was day 2 of quitting the ecig. i would try to lay down and it felt like my heart was beating even faster and a few nights it woke up up at 2 am beating soo fast sending me into another panic mode. i would just keep my xanax by me. now im scared to go to sleep without half a xanax. my husband also had started the ecig and he never smoked the nicotine. Omg of nicotine. he had been smoking it for about 3 months too. One night before bed last week he got a terrible attack where he felt like he couldn't breath. i just talked in through it. it was a bad panick attack. He stopped smoking his ecig too. we have been having terrible acid issues still and its been 8 days since i quite. i cant even drink my coffee in the morning or it will cause my chest to tighten and my heart to go soooo crazy! so now im desparate and drinking a detox water flush i found with cucumbers, oranges, lime, and mint. it has been making my body feel better and the anxiety and tight chest allot less. but even tonight i just had another bad tightening of the chest just sitting here watching tv with my husband. so i chewed my xanax so it would hit me fast and make all the anxiety go away. i want to know how long it has taken for people to overcome this kind of thing and how long does it take to get that pg out of our bodies. it has to be the pg allergy.
