Your 3am Reset is on the way.
Check your inbox in a minute or two. The guide is a PDF, so you can read it on your phone tonight or print it and keep it by the bed.
If you do not see it, look in your junk folder and drag it back into your inbox. That way the next one lands where you will see it.
If the 3am waking has been going on for months
The 3am Reset is for tonight. It steadies the spiral and gets you back to sleep. If your broken nights go back further than that, there is a program built for the deeper version of this. It is called The Insomnia Program. It is audio you play as you lie down, and you follow along. Their promise is a plain one: asleep in under 25 minutes, and asleep through the night, with no fog the next morning. Their order page sets out the guarantee, so you can look before you decide.
