Just me, but my sense of taste was very slow to return. Obviously, strong flavors came through as...something resembling their flavor, but many flavors just didn't register. Basically, accuracy was out the window in comparison to later vaping. It takes time.
Mints, menthol, and lemon or banana were early flavors that I stuck to for flavor.
Someone told me to change my wick more often and not to "cook" my juice with higher power. Juice flavor gets duller over time and changing the wick every 20-30ml did help.
Good luck
