Wondering what caused the buzz? I've never heard of that happening. juice bars normally provide 0 nic flavors, so trying to imagine what would cause a buzz.
So an update for you Kenna. Yes the liquids are different Nicotine levels as you are tasting what you actually buy. I went back today and since it is barely 30 degrees I said forget eating sorbet and brought a nice cold lemon water with me to taste different flavors and I actually found one I liked. The aftertaste of what I did not particularly care for was ruining the taste of the next one. Confirmed it by finding one I liked tasting others without a sip of water but one sip and bad taste was gone. Cleansing the palate worked for me.
