Hi been vapin for 8 months now, never had any probs apart from when I first started,dry throat etc,but that soon went away. I have been mixing my own now for ages, without problems, then tried a premixed juice coz I won it, but it tasted chemically (if there is such a word lol) so stopped using it but I have a couple of large mouth ulcers, does anyone think it is the different juice I tried?? or do vapers get this occasionally??
Thanks in advance.

I had a similar problem from time to time and found it was related to PG, I've cut my PG to the absolute minimum and not had a problem since, may be different for you but worth a try.
It seems there will always be a bit of PG in the mix as some flavours are based on it but I have kept it as low as possible and never knowingly bought anything with PG base as part of the overall ratio.
