So, I am a pack a day smoker. I just bought an e-cig today. It's a stick and not the kind with the big cartridge. I'm sure there are really fancy names but I'm completely clueless. Anyway, I tried 2 different juices in the store prior to buying. The first was fine. When I tried the second I took an even smaller drag and literally thought I was going to die. Inhaling was fine but as soon as I started to exhale I choked. It felt like my lungs closed or something and I couldn't exhale. It felt as though I were choking on a liquid. It only lasted like 3 seconds but I was terrified. I went ahead and bought the e-cig anyway. I tried again when I got home and the same thing happened. The first few hits were fine and then all of a sudden I tried to exhale and totally choked. I couldn't even cough because I couldn't exhale. I really don't want to give up but that is some scary stuff!! Is this normal for beginners?
