A couple of observations and recommendations:
Vaping is not the same as smoking. Most smokers took harder draws on their cigs. E-cig devices require a gentler, longer draw to allow the wicks time to bring the e-liquid to the coils, otherwise you'll get dry or burnt hits.
The very nature of a clearomizer's wicking system sets you up to fail if you are a moderate to heavy vaper, IMHO. Tiny silica wicks can't keep up with you. If this fits you, its time to move up to a better juice delivery device.
I suggest a cartotank. A cartomizer is a steel tube whose entire inside is full of wick and the heating coil. This wicking system can better keep up with a heavy vaper. More flavor and more consistancy.
Using a cartomizer in a cartotank requires that the steel casing have holes to allow the juice in the tank to refill the carto each time you vape. These are called "pre-punched cartomizers". Read the following blog on juice attachments, paying particular attention to cartomizer and cartotank:

If using a fixed voltage device (non-variable power), I recommend low resistance atomizers (cartomizers or coils). These provide a slightly warmer vape.
If using a variable voltage/wattage device, I recommend standard or high resistance coils. These will allow for a wider range of power and be less drain on your battery. These will provide a slightly cooler vape and last longer than a low resistance coil.
