Looking for effective tips on using tret

Tret user but never been consistent and I don't think I had a good technique. Discovering this sub gives me a lot of hope for mild scars. Since many of you have figured out a successful routine, I wanted to ask a few questions

1. How long do you wait after cleansing? I see wildly varying responses from 5-30mins

2. How do you layer? Is it M-T-M, T-M, or just T? If you're layering, how much time between each layer and how thick is each layer?

3. Does "night" mean I can use it after sunset or at lights out? It's easy to be inconsistent when it's the last thing to do. Can't count the number of times I've fallen asleep in that 20min post-cleanse wait.

Does the same routing apply to taz? Considering switching to it.
