I've been cigarette free going on 6 weeks, the issue I'm having is that I got a canker sore about 5 days ago and it's hurts!!! I've increased my water intake since vaping and use biotene mouthwash and tooth paste but damn it's driving me nuts!! I also use ambesol numbing gel but since I chain vape I always drink water and it washes the gel away rather quickly. Wondering if anyone here has had a similar issue, and with vaping making it worse? I've come too far to go back to the stink sticks to turn back now, just looking for someone who has had similar issues, thanks
