Having a regular routine. Waking up, eating, bathing, and going to bed at about the same time every day.

Not falling into the trap of hypomanic seduction. Look out for early warning signs and take immediate action (lay low, take PRNs, get extra sleep, tell pdoc).

Cut down on caffeine

Regular exercise. Nothing feels better than coming back from a 10km run and hanging your legs against the wall, stretching out, taking a hot shower, and just enjoying the endorphins running through your body.
