My only strategies are keep stress to a minimum and avoid triggers. You don't sound like agitation or irritability are huge issues for you so that's a good thing. Keep a routine and exercise (especially as you get older). Exercise is the only thing that balances me out. All of my meds barely do anything. I swim 4-5x week and feel very relaxed and balanced for couple hrs afterwards then I go back to my regular irritable, agitated self but those few hrs are worth it.
