Sounds easy, right? Not so much. The tubes are three inches tall or so, and I have to fill them 1/2 full. An inch and a half of spit, you say? No problem. Go ahead. Give it a try. Try to gather an inch and a half of spit (minus the bubbles - the bubbles don't count). It is a challenge!
The test kit gives you some good tips for helping get "quality spit" for the test. Yawn, chew wax paper, and the one that helped me this morning - sniff a lemon. Well, apparently the lemon has lost its "saliva producing" abilities, because for the noon sample, it wasn't working. I still had dry mouth.
But, alas - I found a solution that borders on the cruel and unusual.
When I sniff Calvin's Chick-fil-a fries, my mouth instantly waters.
Oh, the irony.
