Fwiw, guided meditation practices keep my brain active. A spoken book can calm, but not send me to sleep. Classical music wakes me up. Even the gentle stuff. Drowsy medications have no drowsy effect on me, nor on my DS. Caffeine had a sedative effect when I was drinking it too heavily, but caffeine addiction isn't a good idea. Alcohol does not send me to sleep.

TV sends me to sleep. Very easily. Same for my sister, who also had problems going to sleep. The brain just shuts off as it isn't required. I have no qualms in using it when needed. I know screens are demonised, and I have low screen time rules when necessary, but ask yourself what the problems with screen time are before you get rid of them entirely.
