For me it does.
I recently bought "Gooey Better Cake" from KBV @ 6mg Nic...it's tastes sweet and peppery

like someone threw a piece of Nicorette in there. Now the stuff smells friggin LOVELY, but as soon as I vape it, BLECH!!
I will definitely be ordering a new bottle of GBC sans Nic, just like my other juices. I truly think that I just can't stand the tase of Nic anymore. the only other juice that I have nic in is my Ice Menthol from Smokeless image. I can only vape that for a few minutes before I start feeling Zesty, lol
