I’m only a user of subs, but my immediate answer would be yes.
For one, the subconscious is active 24/7. That’s what’s always running us. I am guilty of getting in my way a lot. I’ve noticed that when I step back from consciously trying to steer results, subs I use tend to bloom more.
I’ve found that with both love subs and sexual subs. Fears constantly trying to meddle and interfere. When I’m too mentally exhausted to meddle, that’s when results become very obvious.
Edit: I just realized St.1 was a very busy subliminal, as it constantly poked and prodded the things I"ve avoided or protected all my life. Having said that, sleep came easy while on St.1. So were naps.
But being tired actually allowed it to work on me more. I found myself semi-dreaming while awake at times. I had great desires at times to just pull off a work assignment and sleep.
