I was in your position a few years ago. If it comes back, you need to understand why. you don't "catch" a fungal infectin like you catch a cold. before the fungus takes root, the conditions have to be right. and, if the conditions are right, just killing the fungus brings only temporary relief as it is soon back. the truth about fungal sinus problems is that they start deep in your gut... sometimes a food allergy , or else just years of eating foods that are not the best for you. look for a few of my old messages if your problem creeps back. liverflushing, lymph massage... diet. I lived in Andreas Moritz forum here for awhile, more healing info than you will ever need.
