I haven't been able to master the nedi pot, but my old stand by was to go out in the back yard and dig up a hunk of Horse radish.
Spin it in the Vitamix with a touch of sugar, water, vinegar.
Pray a little, grab a paper towel and eat one heaping tea spoon.
Very quickly all passages open and any mucous is released with prejudice.
Don't forget to pop your eyes back into their sockets before you try to get up off the floor.
Yes I have done this. It works, and yes it is briefly painful.
The radish must be fresh 90% of the store bought stuff is just too weak.
Feel better soon.
