I've been using VG based 26, but recently ordered some my freedom smokes PG 36, much stronger - so strong in fact that I can only take a few puffs at a time and have to set it down. I've had 36 before but this seems even stronger than I remember. After a few days of use I noticed a small canker sore underneath my tongue. I'm starting to wonder if it could have been caused by the sudden nicotine hike using 36mg (really strong) liquid. I've used PG before so I don't think it was the VG to PG switch that did it. Also, I recently started vaping again just a few weeks ago. I'm hoping it goes away soon. Any ideas or similar issues?
