Maybe it's just because I've been vaping mostly light flavors... but I find that after taking a few puffs of a juice, I can't really taste it anymore. I end up having to wait a bit or add more liquid before I can taste it. Instead I just taste an almost metallic, burnt taste, which isn't pleasant. Has anyone else noticed this? 
BTW... I'm direct dripping if that has anything to do with it.
