When I just started with LifeFlow, I wanted to cure my insomnia.
I meditated in bed, listening to LifeFlow and went sound asleep every single time.
I slept perfectly and cured my insomnia
So, from personal experience: GO FOR IT
All I would like to advice you is, don't put it on repeat, your sleep can go deeper than LF 10's frequency, so if you would listen to LF 10 all the time while still asleep, your sleep would be less benificiary.
