I've sort of been winging it since 2011, no concrete plan so to say. Just knew that for various reasons meds had to be flushed...
I'll share what comes to mind though
Anxiety (the skin crawling kind) exercise or hot shower works wonders.
When I'm hypomanic, I do my best to expel the energy as quickly as possible. Cleaning frenzies, dance-a-thons, loud music (accompanied by my loud singing of course!), give my plastic to someone safe so I don't go on a spending spree, meditation or visualization (to calm the racing thoughts). Buut, I get very dysphoric after a while, so hypomania also includes locking myself up for a few hrs with metal on fullblast, and a new one I'm trying is holding my breath while choosing how to respond.
Sleep schedule is important, make sure you get the amount you need. Routine is super important, most people will testify that things turn to shyt if there's no routine involved. Routine helps because our moods are inconsistant, but we still need to function consistantly.
Opposite actions: Very helpful for any cycle that leads you to less than desirable actions. i.e; I'm really depressed I want to lie in bed all day... Get up and go for a run instead, the first action is the hardest because it's forced, but it will lead to others that come more naturally.
Mindfulness and Grounding techniques, works wonders for staying in the moment and not letting a situation completely overwhelm you.
Stress: WE ARE ALLERGIC. Remember this, stress is a sure fire way of triggering an episode.
Avoiding stress is impossible, but do your best to pick your battles wisely.
Breaking stressful situations into smaller doable chunks goes a long way with avoiding being overwhelmed and don't forget to breath... I do

its embarrassing, but I'm getting better at being mindful of my breathing and my posture. The state of my shoulders says alot about my state of mind

Depression: Healthy hedonism is a beautiful thing. When the world has gone to shyt and you have no reason to live, have a luxurious bubblebath, go to your favourite baker and get the most decadent slice of cake. Buy yourself something nice just because.
We forget to be nice to ourselves, and setting aside me time and doing nice things for ourselves is really helpful, because we remind ourselves that we matter too, that we really are worthy... even if the message is subconcious, it's still well received by the brain
Agitation? I'm sorry I got nothing, I'm still at lock myself up like a caged animal stage. I do this so I don't hurt anyone's feelings with my non existant fuse and foul mouth
B12 injections have really helped me. I used to get a double dosage once a month, my symptoms have increased significantly since I stopped. I don't claim to know the science behind it, just took advice I got from people I trust here, and a gp too.
Triggers: If you haven't already, learn them!
Some we can face head on and work through, others should be avoided. Example, I'll do something I have to, that leads to me being triggered if the ramifications are short lived, like large crowds may trigger a panic attack or lots of anxiety... I will however not ever again put myself in the position of feeling trapped. My last job did that (not the job itself, the nature, of it) and it was 9 months of struggling to cope.
If alcohol or caffeine is triggering, cut down / cut out, depending on severity of trigger and your personal choice of course!
Mood Tracking helps some people as cycles usually have a pattern and it helps identify triggers, if there were any. Me? no, I know how I cycle, but prefer not to be focused on bp at all. I give it as little attention as possible because I struggle with balance and last time I allowed it to consume me.
Uhm ok, my phone is having a seizure now, it hates such long essays!
And a warm

to you
