Is there such a thing a over vaping? I am quite new after a few weeks found a juice that I liked a certain reputable companie's 555 100% VG, did it constantly, now I am about halfway down the bottle and it doesn't have the sweet nutty taste anymore, thought it was a cartomizer issue so I switched cartomizers, thought it was a juice issue so I tried another brand new bottle. My first hit of the morning still has the great taste but after just a rotten taste. Any ideas? FYI I use a KR808D1.
