So This past couple of months vaping has been making me gag and makes me want to vomit. I get close to vomiting and I start coughing alot. This has not happend before I used to smoke cigs and I never had that problem either. I started using a mod a couple months back and I didnt have a problem with that either. I use 3-6 nicotine so I know its not that. Can anyone explain this its really annoying and I hate it. Ive been vaping for over a year
