Idk about alternative therapy but I stick true to three things when meds aren't enough

1) go to sleep the same time every day. I notice this gets messed up when I experience symptoms and SOMETIMES the sleep problems start even before the mood symptoms begin, I believe they play a role in how the episodes develop.

2) I maintain a strong routine game when it comes to anything that disrupts sleep. This includes avoiding alcohol and caffeine in the afternoon, but also extends to healthy and reasonable social activity levels and stress, which also can have an effect on sleeping patterns. I don't really travel much, but I would like to, the jet lag alone would kill me. Also daylight savings time is a big disruptor, but not much can be done about that.

3) Whenever things get weird, i take a look at wether or not I've had disruptions in things related to sleep, and I try to get back to my usual routine as fast as possible. If I take action at the start of those issues developing, I tend to stabilize back a lot sooner.

Unfortunately, symptoms themselves can really **** with being able to self-manage and follow a routine, and it could reach a critical point where it makes no difference. So identifying (i wouldn't call them triggers) the risk factors at play as soon as they come into the picture, and before the symptoms reach that critical point, is key.

Hope this helps
