I have been thinking the same. when I first tried RY4 I thought it was sooo yummy and tasted like cotton candy. Now I find myself mixing in menthol vanilla trying to get that same flavor as the first time I vaped it which I just added to a cart that appeared empty but was used with Vanilla and Menthol prior. I hardly notice the cotton candy flavor any more, but it is still pretty tasty. Oh, sometimes I don't inhale and let the vape sit in my mouth so I can taste it which helps...
Thinking our taste buds get use to it and I will need to switch up flavors and I just ordered a ton of RY4. Maybe I was vaping it more like a cigar when I first got it and not inhaling as much.
Come to think of it I had 2 901's loaded with the stuff and it tasted so much better in one of them for some reason (when I first got the RY4). Maybe I am just not getting the mix right... I keep trying only the RY4, then I try mixing with some menthol, then I try mixing with some vanilla. But usually the RY4 on it's own taste good a little menthol helps the throat hit and makes it smoother and cooler...
I also have the sample pack coming from JC and a couple hundred dollars in RY4, capuccino, menthol, cream from another suppler of e-liquid. I should have plenty of juice to play with next week.
Man, I am like 1,500 bucks into all this stuff in a couple of weeks between my wife and I and fear of the FDA (oh this includes the original 250 bucks I wasted at the kiosk in the mall to get started which bought me (1) super mini e-cig kit (401??) and some nasty juice that taste like a wet dog, LOL)...
