Sugarless

The doc says these recurrent sinus troubles I've been suffering for a brazillion years now may be fungal rather than allergic.  Things that make you go, eeew!  I have a mental image of moss, mold, and mushrooms growing in my face.  (Mosses aren't fungi, but we're talking imagination here, not biology class.)
The doc recommended using a neti-pot.  I don't want to!  If I pour liquid into myself, it should be in my mouth, and it should be tasty.  My mom suggested a neti-pot some time ago.  I told my mom I was hesitant to try any home remedy from someone who grew up in the sixties, particularly a remedy using the word "pot".  My mom slapped my caboose with a kitchen utensil.
Fungus, naturally, feeds on sugar.  So guess what I'm not supposed to ingest?  SO unfair.  I'll discuss my indignation at this outrage with my uncle tomorrow morning during our weekly sixteen-ounce sweetened caffeines.  He will understand, and we will drink lattes in protest.
Meanwhile, I need to decide what to do about Pixie and Angel Doll.  They incessantly produce sugaries.  Pies.  Cookies.  Brownies.  Cakes.  Bars.  No-bakes.  They make up their own recipes, for heaven's sake.  As Mama, I am obligated to be supportive of my daughters' endeavors, and taste-test said sugaries.  There are sugar substitutes out there, but none of them like me and that hurts my feeling.  (I only have one.)
Should I compromise my conviction that nothing should ever be poured up my nose?  Will I lay off the sugar and starve out the fungus?  Must I spurn my children's talents in the kitchen?  Might I die from dessert deprivation?  Am I willing to put Nesquik, Hershey's, and Reese's into decline?  What Would Jeremy Renner Do?
