I've been at this for just over 3 weeks and the closest I've found to an all day vape is ECBlends' Ry4. I know Ry4 is a tobacco blend, but I don't taste any tobacco in it and that's just fine with me. I haven't liked any of the tobacco flavors I've tried. The ECB Ry4 doesn't have much taste (to me), but it gives me the throat hit and sensation of smoking much more than any other juice I've tried. BTW, my bottle is 18mg nicotine, 60/40 pg/vg, with extra caramel flavor.
I also like ECB's Dragon's Blood. But I got mine in a 12mg nicotine and it doesn't have enough throat hit. When I re-order, I'll get it in 18mg and that should be just about perfect.
