Starting about 6 hours ago, my french vanilla which I have been vaping the last week and a half, started tasting like absolutely nothing... Just air, and occasionally a water taste... So I tried mixing my french vanilla with banana, and it taste like... things I can't say on this forum... I've also noticed a almost constant metal scent... I've only been vaping almost consistantly for the the last 3 days, only smoking 7 cigarettes in that time, if that is of any importance. Peanut butter however, still taste perfectly yummy...
