Atomizers are absolutely what you are looking for. What battery do you use? Do you know if it's a 510 eGo threading? If so, I recommend genuine Joyetech atomizers.
If you're using a fixed voltage device, such as a normal eGo, I would suggest getting a "low resistance" atomizer within the 1.5-1.8 ohm range.
If you have a variable voltage device, and you like vaping at higher voltages, I suggest "standard" or "high resistance" atomizers within the 2.0-3.0 ohm range.
If my second statement confused you big time, you're using a fixed voltage battery and I suggest you get yourself at least a handful of genuine Joyetech 510 low resistance atomizers. Super easy to clean, and man, do they make your juice taste
deLISCious.
EDIT: Forgot to suggest how to use an atomizer. Basically you just screw it onto your battery just like any other tank or carto, drip 2-3 drops of your juice directly into the atomizer (yes, the middle is perfectly fine), pop on your 510 drip tip (you absolutely MUST have a drip tip, it's a neccesity with atomizers), let it sit for a couple of seconds, they puff away. You typically get three-four really good hits, but then it'll immediately taste burnt. This is ok. All you need to do is either drip the juice back down your drip tip (I prefer popping the tip off, dripping directly into the atomizer, then replacing the drip tip. Avoid juice-in-mouth that way). They don't last forever, but mine have lasted a good two months.
P.S. A lot of people use "cones" to screw over the atomizer to protect the battery from dripping (

Hope this helps.
