DMSI: Can it be used during sleep?

[RTBoss]

Any difference in efficacy between use during the day (awake) or alseep?

Not in efficiency, but it may make it harder for your brain to get a decent amount of rest if you're constantly putting it to use.

I am experiencing that currently.

Efficacy, not efficiency.

As Lowe states, no, there shouldn't be any difference in efficacy. You can test it and see what works best for you. Don't overthink this. Just get your 2 loops in every day.
