You may want to set your airflow control a little more open once you clean it out. If airflow control is too tight there is too much vacuum when you inhale and it will flood.
Also with my devices I eventually get buildup in my drip tips just from vaping, so I tend to clean out my drip tips once per day as well or I get a little bit of juice in my mouth. If its not gurgling then it may just be that
Those are the two things that come to mind without more details I guess
