I've been DIY Hangsen tobacco juices for almost a year now and have many commercial juices I use to vape and like but can't tolerate the over sweetness of the juices, I have PIF most of them away. The biggest benefit other than saving money from making my own juice is that I'm not parched anymore and only drink a fraction of the water I use to when vaping commercial juices. IMO most of the drymouth experienced by vapers is from the high sweet content of the juices they vape.
