I'm concerned about the flavor from my liquids. Been buying from a local b&m. After vaping for a couple day they loose flavor, then twords end of the week can hardly taste at all. I make sure I drink lots of water, always have even before getting off the stinkies. What really concerns me is now a couple weeks later I bought one I loved a cou up le weeks ago and can hardly taste from the start. Using Tesla vv/vw with a nautilus mini. Have cleaned with vodka, boiled and changed heads. Any ideas welcome. Thanks
