Does Nic level change the taste?

The higher nic level you go, the harsher,stronger, more flavorful they are. PG/VG ratio can also affect it. As can how hard your drags are. Easiest thing to do right now is try taking softer slower drags. And I would also put in an order for some .6% and 1.2% of your favorite flavor to find the right strength for you.
