Vaporizer making my throat dry

[lovingdagreen]

Hi guys

I have a Volcano Vaporizer - ive had it for a couple of years now but when I use it then my throat gets all irritated and dry. I've tried setting it at different temps and also sip water before and after but no joy -

I tend to be good for the first couple of bags but then It gets too bad.

any advise would be appreciated
