I definitely noticed it early on, but I think much depends on the juice. E.g. there's a raspberry lemonade that I'l liking quite a bit now that that strays toward "just sweet" after 12-18 ml. Vapor production is still fine, but the citrus bite goes away after a while. Pull wick, dry burn, re-wick, and it comes right back.Anyone else find it interesting that suddenly no one has been saying that rayon adds a sweet note to the juice?
I personally never experienced it, so I was always curious
For me there's another side effect of rayon in the tiny chambers of the Cyclones I run on my bottom-feeders: I water down many of my juices with unflavored now; some as much as 50%. I find I simply don't need the amount of flavor I used to.
