Oh yes, I think a lot of us may go through that. I have had periods of time when I could taste absolutely none of my flavors. My first major discovery was that I was using a flavored denture adhesive which was masking flavor. Next one I found was a powerful oil wick air freshener. I removed/changed those things and that imroved things very much. Denture adhesive has a no flavor/no color/no zinc choice in the Poligrip line, if anyone needs to know. Next I found that once a clearomizer has reached it's maturity, it will lose the ability to give good flavor, no matter how clean it is. It's time to trash it, and move on to a new one. Amazing how that will improve the flavor for you. I don't use atty's anymore, they were too hard to clean out. I use Kangers now, with each dedicated to one flavor. I use little stickers to identify which is which, or sometimes the color of the tube will be the identifier. I have used a dot of different colored nail polish as a code also. Anyway, hope this info helps.
