Hello, I'm Tom.
been vaping for about 4 months now - sometimes I love it, sometimes I hate it!
don't miss the fag smell, but don't much like the dreaded side effects - dry mouth / dehydrated and now cankers.
at least I can vape in the house!!
Ok... I had the same problem. I couldn't figure out what it was either until someone here mentioned that I maybe allergic to one of those three items I mentioned. I was about to give up as well when I ran into an old friend. He and I quit smoking the same time and so we both frequented the same shops. I asked how he was doing and I mentioned that I haven't seen him in a while, and he begins to tell me why. He had the same problem I was having and he learned that he was allergic to the nicotine that was being used in most of the vape shops we went to. He also found out that that the most of the shops we haunted had the same supplier for their juice. So, my friend just stopped going to the vape shop for his juice. He is now making his own and buys online from reputable companies. I wasn't ready to do that but I did narrow it down to 2 shops and the sores went away. I also went to a 30pg/70vg as well as knocked my Nic dosage to 18mg. That helped with the dry mouth. Have you tried anything like that?
