Hi Tab... glad to see that you figured out the issue. Having never used an aluminum drip tip that one would have gotten by me. =)
Still, there is some excellent advice in this thread should the problem recur. Specifically, Malyden's post covers nearly all the bases, as it always does. (it's always a good idea to take a look at the poster's avatar and info to see how long they have been around, btw. Malyden has been around a loooong time and was one of the people I followed way back when)
Women of Heart made a comment that shouldn't be missed either. That is, we all seem to experience times where nothing tastes right, no matter what you do, and it can last a few days. That's usually the time when I'll reach for a menthol or lemon e-liquid to sort of clean the palate.
The only thing I'll add to this is that it's important NOT to lock yourself into one flavor of e-liquid. I think I searched for my
vaping *brand* for months until I realized it just *ain't* like smoking Marlboros. LOL
Mix it up and have some fun. Best of luck to you!
