Despite my strong desire to blow my nose immediately after irrigating, I
find that irrigation works best for me if I don't blow at all for at least
20 minutes and that I do best when I let the fluid drain out without any
force. After 20 mins or so, I then tilt my head side to side or bend over
forward with head down to promote the natural outflow of any remaining
saline fluid. After doing this, I might then blow very very gently to clear
out my nose a bit. If I blow my nose at all right after irrigating, my inner
ear/ears sometimes feel weird perhaps like there is still fluid trapped
inside and I suspect this is also what might be happening to you.

If you've only irrigated 5-6 times, then something probably still feels odd
after every irrigation. I didn't get my own irrigation routine down until I
had been irrigating twice daily for several months.            AW
