I'm having one of those days where nothing seems to 'hit the spot' when I vape. I carry 4 different flavors in case I get surprised with a vapors tongue. A mix of juicy fruit and dragon fruit, caramel tobacco, a cinnamon menthol and a papaya strawbango. None of them seem to have any taste except the cinammon menthol but it still tastes wrong. All tanks are bottom fed ( I know doesn't give the strongest flavor) but previously they each tasted strong and great. Any ideas ppl??
