I had been vaping for about a month when I started getting the scary side effects that I heard can occur from the PG vapors. The jitters, insomnia, chest pain and palpitations ect. I was only using a 6mg nic level so know that was not the problem. I got rid of all my juices (broke my heart) and immediately took the advice of many ECF members and ordered 100% VG juices from some recommended websites. Only problem is...now I'm scared to try again. I know this is a common problem from what I read here but any positive input from anyone with the same problem would be appreciated and hopefully prompt me to try again... I desperately do not want to go back to smoking!!
