So I started vaping about 4 months ago in January. I bought a Juul and mostly just vaped for the buzz that the Juul gives. But over the past months I've been having constant chest pains, constant bloating and sore neck muscles as well as now I have trouble breathing. Never in my life have I had any problems with these things so I am 100% sure it's due to vaping. I've gone through so much Tums/PPI's and simethicone within the past months, but nothing makes it go away except when I stop vaping altogether. I went to the doctor and everything is fine I got an ECG ect. Do I have some sort of intolerance to PG? or something. I don't vape all day either just a couple puffs here and there. But when I do, I usually take 3 straight lungs hits and hold it in to get a good rush. I tried to just do mouth to lung but that also causes the same problems. I don't want to give up the Juul at this point but what should I do? Should i get an unflavored juice or max VG/PG?
