I started trying vaping about 2 weeks ago. I'm not getting the same lasting effects from the nicotine as I did from analogs therefore, I'm still smoking analogs along with vaping. Am I doing something wrong or do you have to vape more frequently than you smoked? I'm currently using the Sensation from eSmoke & 16mg cartimizers. I regularly smoke Light 100's so I thought the 16mg would be equivalent. I normally smoked about 15 Cigs a day & I would go about an hour or more between cigs. The e-cig only seems to satisfy my nic urge for about a half hour & I vape for about 8 min. I'm waiting for the arrival of an order from V4L where I ordered a KR808-D1 and 24 mg. Cartos. Maybe I will have better luck with that. I really want this to work for me.
