I have been asking questions recently about my mouth and tongue burning. I have gotten some great advice and have tried them all. I drink a gallon of water a day, using high vg all natural juice, no artificial flavoring, lowered my nic level and using biotene. It does seem like it got a little better for a while since using the natural flavors. I have been using the ego twist for about a year off and on and never really had this problem. I bought the istick 20 and nautilus mini because I have never really gotten a whole lot of taste from my ego and small carto. My question is can it be this set up that is burning my mouth? Is it that much stronger? When I bought it they told me to run it between 8-10 watts. The atomizer is 1.8. Thanks for all the help!!
