I'm a not exactly a new vaper but I feel my question is best left here. I vape on a SMOK stick V8 and I have noticed I am going through 150 ml of juice in about 5-7 days. That's over $50 a week in just juice!!!! A carton of cigarettes is cheaper than that! My question is why am I going through so much? I'm on a 3 mg nicotine level because I choke on anything higher. I change my coil once every 2 weeks as suggested by my local shop. Am I doing something wrong or am I just not realizing how much I vape? HELP!!!
