if i may suggest something you've tried a different atty and it improved a bit sounds like you need a pallette cleanse if you have any menthol or mint juices try vaping some of that for a while it often helps when a flavour seems to have become disgusting or just loses its flavour.
good luck hope you get it sorted x19silent79x
When I first started vaping, only 14 days ago, some of the ecigs or cigalike flavours tasted really nasty. Synthetic, artificial, chemically and some tasted of rubber also.
