Hi @
MangoPassion:
I usually zonk out right after getting comfortable in bed. But there are breathing techniques that can help.
One is to breathe a bit slower and focus on making the duration of the inhalation the same as the exhalation.
Another (which I just learned about in the Finch app) is to inhale to a count of four, hold the breath for a count of 6 and then breathe out to a count of 6. I'm yawning just thinking about this.
I'd add onto @
Deejay14's good advice about avoiding caffeine too late in the day and say that some OTC drugs such as Exedrine can contain caffeine. Also avoid chocolate in the evening and take antidepressants in the morning. All this assumes you're trying to sleep at night.
