Exciting news! 
I’m looking forward to hearing how it goes!
I usually apply the creme after a shower, which I usually do in the morning. But as I mentioned, I don’t really have any fanatic schedule or routine. Some days, I wont use it at all, and sometimes I will feel a SD-sort of sensation on my skin or notice small signs of irritation or redness and just apply some before bedtime to be proactive - maybe even without a face-wash. One thing I try to do, though, is to complete at least 4 days of treatment if I feel the need, in order to combat resistance. It’s just something that I do, not something I was told to do, but I reason that small doses once in a while might select for the more resistant fungi. Sort of like with other antibiotics, where you have to complete a full treatment, even after the symptoms disappear. But you don’t have to worry about that at first, as you should use it daily for at least 2 weeks, I’d say. By then, if it’s effective for you, I hope that you are almost back to your normal self
Initially, I might even have used it twice daily. I actually cannot recall. But I do remember my dermatologist saying that you don’t really have to be worried about using “too much” - not like with hydrocortisone. So you can do that, if you feel like it - morning and evening. That doesn’t mean, however, that I applied a face mask of nystatin to my face every night. Just work it into the skin wherever there’s inflammation. I use less than a pea now, but maybe a pea-sized ball is alright in the beginning. You’ll figure it out. But work it in gently, don’t leave a layer on the skin. And then you’ll diminish your consumption down the road. I’m only on my second tube after using it on-and-off for a year now.
I have not had a full-blown flare-up since forever, so I can’t actually tell if it would comeback if I completely discontinued the use of nystatin. The reason I still use it from time to time is just to be proactive and because I already have it. I’ve been very casual with the use during summer without problems. Last spring, however, I had a flare-up, but maybe it wont happen again? Maybe my hormone levels have changed – and with that the composition of my nose-lipids --, maybe I’m not as stressed anymore, maybe by using nystatin I have helped my body reestablish a natural balance that it can now maintain after this initial, helpful push. I will find out, I guess, when I finish this tube. I might go cold-turkey for a while then, and only buy a new one if it returns.
The trip to the Philippines is an example of the horrible self-diagnosis one can perform when dealing with SD. The effect was non-negotiable: The SD disappeared. But I changed SO MANY things. I was living in Beijing at the time, studying, and went on vacation to the Philippines. So my diet changed from Chinese food to Filipino food, my environment changed (sea water, more direct sun-light, less pollution, being outside much more, etc.), I went from stressful work to relaxing holiday and so many other factors. There’s no real conclusion to be drawn from the trip except that something – one or more of those changes – had actually made the SD go into remission. That’s the one thing I gained from that: That it was possible to treat. And that gave me hope and motivation to keep looking for a solution.
End of speculations for now – work’s a-calling
But good luck with the treatment! I wish you all the best.
Imagine: in a week or two, it might be all gone 
Just in time for Christmas!
Thanks guys!
