Look up on google images "vaping power chart 2.0" should be the first image, that'll show what ohm to volt you should use but if you mean the liquid burning too fast as in runs out too fast I would try messing with the vg to pg content you use and find the best ratio. I usually use 50% (going for long lasting with the least amount of liquid) and at that level a 3.0 ml tank lasts me about 2 days, and yes I smoke on it constantly.
