I'm the exact opposite from @Bebop. I tend to stick to fruit based flavors as my ADV's and occasionally mix it up with the coffee flavors and "dessert" flavors. To this day, more than 2 years after I started vaping, one of my favorite ADV's is the very first one I ever tried and is from a local shop - Lemon & menthol.
I do get "vaper's tongue" though, no matter how hydrated I stay. When that happens, I will typically switch from berry to citrus or vice versa for a few days or I'll vape something pastry or dessert flavored for a couple of days and that will usually take care of it.
Other than that, I have never been able to find a single juice that is my "be all, end all". Not even that very first juice I tried. In this case, the only thing I can think of is that, while your taste buds are working again, it's possible you may be confusing the heck out of them with all of the different flavors you're throwing at them.
