I don't know what (if anything) I'm doing wrong.

I tried the Netti-pot. Each time there was no difficulty using it. The fluid
went in one nostril and easily out the other. Not a lot of gook came
out--pretty clear, which I expected. It felt fine doing it, but:

1) After the first time, severe headache that lasted about 4 hours. Tylenol
finally knocked it out and next morning the headache was gone.

2) After the second time, the infection seemed to spread higher up (usually
I get post nasal drip, sore throat, fatigue, etc.). This time sinuses hurt
like hell, felt raw, sneezing, and just overall misery like those
commercials for the common cold. That has lasted for 3 days and while better
it is still not right.

Question: I am almost ready to give up irrigation (the Grossan thingy never
really seemed to help; I do have the NeilMed on order so I might try that).
For the netti-pot (made by Neil-Med) I was using their solution. Somebody
here posted that it was too harsh. It didn't feel harsh while using it, but
is it possible that the mix is what's causing my problems? If so, any
suggestions on some simple solution to try.
