Interesting... sounds like you are doing really well!
It's a shame about the tobacco extraction though, that must have been a bit frustrating. It's funny i never really liked the taste of cigarettes and always chased a smoke with a drink to take the taste away. So i don't think i'll ever try to find a tobacco flavour to vape. Ales, good lagers and wines are another matter though, i love the taste of a good quality tipple.
I've just spotted a beer flavour which i think i'll sample
The mouth issues are strange, i was expecting some ulcers/canker sores and got them, but they came and went in a cycle for the first six months. One week without then one week with. I've occasionally had two weeks without but the cycle persists still. I'm currently on a week with that is just starting to end and i'll probably be fine by the time i get to the docs tomorrow
I've read a ton of threads on here in the past few days and the only scenarios i kind find that are pretty much the same as mine a change of toothpaste was the cure. I'm not going to do anything before speaking to a quack tomorrow though.
