I have been using my DCT cartotank for a while now. It used to go for a long while before I had to change the cartomizer in it but now even with a brand new cartomizer I start getting juice in my mouth within maybe 10 to 15 minutes. I have been going through cartomizers like crazy. I am not sure what the problem is? Is it the tank or is it the cartomizers I am using? why does it over flow so quickly? Please help. Thank you.
