Ultimately, subdrop occurs because of hormonal imbalances/receptor overloads, so how to prevent them or predict when they would occur is very individualistic. However, generally we know where it comes from and some things that can help.
Here is an article that explains sub-drop in deliberately over-simplied terms:

Here is another article throwing out some ideas for managing sub-drop:

Generally, I think these tips can work even if you're just feeling down.

For your questions:
- whatās the first indicator for you that youāre gonna drop? Is it consistent from time to time?
You don't always know you're going to drop, but it is a good idea to be prepared for it if you have a particularly euphoric/emotionally intense experience. It won't necessarily be consistent as you won't always be able to quantify euphoria. You won't be able to say, oh, I am 113% happier than I've ever been, or today was 87% as enjoyable as yesterday. So, in that way it is tough. Just be aware of your feelings, especially around emotionally intense ("positive") situations.
- Whats your plan if you drop? (Especially if youāre coping alone.)
The articles above have some suggestions and others can do so as well. Personally, if a sub of mine drops, aftercare and a lot of communication is the way to go, and I may suggest doing certain things and keep checking in. It is very individualistic. I don't have a set of very specific things I always do. Generally there is a direction you want to go into, but specifically activities may vary somewhat.
- Any must-haves for the care kit? (Please, tell me to buy more squishmallows.)
If squishmallows make you happy and calm you down and get you out of your head, then yes, buy more squishmallows. Other ideas for what to have in a care kit are at the above links.
Hope that helps.
