Hello everyone, long time lurker. I have unfortunately had a very bad experience with vaping and I just wanted to share with everyone and see if anyone had anything similar happen to them. I have seen many posts on here that have talked about SOB but all responses chalked it up to either Nic or, PG/VG levels too high/allergic to them. I was vaping for over a year when I had my first bout with SOB. I was running a Smok alien with a TFV12-T8 at around 165w. Now I was using this for a while when all of a sudden I started to have SOB. Nothing too terrible but it was enough for me to quite for a while. After about 4 months off of it I decided to pick it up again so I bought a little Smok V8 pen vape. No problems what so ever. I ended up dropping the V8 and damaging it so I bought the mini alien, loaded it up, and took a hit. Instantly had the SOB feeling except much worse. I feel as though I can't take a full yawn, like they aren't satisfying my need to yawn. In order to take a full breath I have to really force it. It has been almost 2 weeks and it seems to be getting a little better but I am definitely not 100%. I have not made an appointment yet to see a doc, I have a few personal matters to attend to and if it is not resolved by then (about a week from now) I will make the appointment. I should mention that both times I was using silver back lola 3 nic. Anyways, I was wondering if anyone has had something similar to this happen to them and if their docs found anything. It sucks too because I really did enjoy vaping.
