Idk why but I have a hard time vaping one flavor for more than two to three days. Its like when I vape a consistent amount of one flavor it seems to "disappear " sometimes in the same day. So I constantly change tanks and juices because it leaves me tasting nothing after a while. It doesn't matter whether PG or VG. All except dripping. Dripping is the only constant flavor for me. I vape halo and alien visions. Bobas, gorilla juice...HX3 torque prime Tribeca.Capt Jack. All of it which never tastes as good as it did when I first start vaping it. Fresh cartos or older makes no difference. Not sure maybe its just me.
