Recovering from the worse case of thrush of mouth and tongue of my life. What to do going forward?

This is the 3rd time I've had thrush of the mouth and tongue since 2024. Each time has coincided with a bad illness. The first time was while having Covid, it took two trips to the urgent care to get it diagnosed and for a doctor to prescribe me Nystatin oral suppression. The 2nd round of it came 8 months later in 2024, again with a bad cold / sinus infection.

After the 2nd time I took probiotics for 90 days thinking that was enough to crowd out Candida in my gut biome. Nope. About a year and a half later I get it again (this time) while once again during a nasty cold + sinus infection. I should point out that this doesn't happen with every cold, even had Covid 2 more times between the last time and didn't happen then.

This time has been the worse. Extreme tongue pain with a heavy greenish white coating, pain around the mouth. This time it also went to my lips and I'm embarrassed to even say this but to my penis as well. Yeah, who would think that thrush can go to ones southern regions. That actually happened the first time. Well just like the first time a white film developed over my penis, same type as the skin looking type film around the corner of my lips. This time some of it went right over where one urinates...yeah extremely painful. Took several baths and had to remove some of the film with tweezers which was painful. Never seen my penis bleed before, it did this time a bit from this mess.

Like the previous two times Nystatin oral suppression is helping to knock this out. Doctor put me on Nystatin and Amoxicillin (for the sinus infection). On day 3 of Nystatin and finally starting to feel some minor relief. You take it for 14 days 4x a day. Have lost 15lbs during this as it's too painful to eat, too painful to talk to. Imagine having to text your wife in the house as you can't speak to her. We have a 3 year old toddler (who I caught the original bad cold from, he had it really bad, just no thrush thankfully) who I can't talk to as well beyond mumbling a few works.

Is there anything else I can do to prevent this from coming back? I read that overconsuming sugary foods and drinks along with poor oral hygiene can contribute to Candida yeast overgrowth. Over the past 2 years I've gained a good amount of weight and eat too much processed sugary foods. That's over today, I never want to have this type of pain again. You don't realize how good any type of food and simply talking is until you can't have either. Also only was brushing once a day, that's done (at least twice) as well as swapping out tooth brushes more frequently.

Hope this post helps others that have dealt or are dealing with thrush right now. I wouldn't wish this type of pain on anyone.
