This is my second round of quitting smoking. The first one was late last year, and I lasted 3 weeks. I don't recall having any adverse reactions to any of the pg or vg liquids I had tried, but now I seem to be having a semi-sore throat for the past week or 2. I've been to the doctor who has said my throat looked fine, but when I took a look at it myself, it looks far from it...white patches on the very very back of my throat, behind the uvula. Has anyone else experienced this. I've read numerous posts on pg causing some throat issues if not enough water is drank while vaping...this is my first thought. if not, maybe I'll just go visit an ENT and have it checked out.
