Tip: after filling your tank, get a napkin and blow through the drip tip slowly. This will expelled any extra juice you have gotten in the center air area. (Reason your sucking juice is likely this) the excess juice will come out of the air holes in the bottom of the atomizer. This should solve your problem. You can do this after every fill or any time that you are flooded. Your flooded if your sucking juice likelly. Hope this helps and best wishes.
