Do you chain vape? If so, you may be getting more nicotine than you should. One solution for me has been to buy e-juice with a lower nicotine level. Most vape stores will sell e-juice with 0 nicotine as well.
My favorite store is Volcano Ecig. You can get some coupons for this vape store by going to http://e-cigbargains.com/volcanoecig/. They have a lot of unique e-juice flavors from Hawaii.
