RY4 stinks as medical tray at dentist;
I couldn't agree more, RY4 is disgusting, it is the certain type of clove oil extract used in the RY4 flavoring, basically the same stuff Dentists use as a numbing agent and an antimicrobial topical solution to prevent infection.
Wherever you got those flavors from find a different site or a few different sites and get some samplers. RY4 no matter who makes it and all the variants of it all have that nasty flavor and smell.
