hey flip, I have that happen all the time the newness wears off quickly for me as well. I had this some kind of blue something or other juice from a shop around here, it was a strong grape flavor, like a grade soda or snowball. Even with that, the taste would go away. I read all the way through this thread and it is loooonggggg. But there is lots of info. I had trouble with my STm for about two weeks, I went through a box of OCCs in no time. Now I know how to rebuild the OCCs, but mostly I learned the RBA is so much easier to deal with. Better air flow and flavor. I usually follow these steps when it's time to refill. Turn it upside down and remove the tank, maybe rinse the tank out, remove the RBA cover and pull out the wick if it looks at all discolored from a burn or whatever, rinse it all under hot water, blow it dry, put it back together and I pulse the coil a couple times to see if it is working well, turn the battery off(yeah I learned that pretty fast) and rewick. There are a lot of rewicking procedures throughout this thread, or do a you tube search, the vids will show up. Make sure you prime the wick well, don't flood or fill it up, but nice and saturated. Before I fill the tank and put it back together I will pulse it a few times to help get everything flowing. Sorry for the jumble.
