I read some interesting stories about long-distance relationships on the Internet. Both sides will usually make voice calls hands-free all night, which will bring a sense of safety in the darkness to each other. They will fall asleep hearing the breath of the other side falling asleep and sometimes whisper softly beside the mobile phone. This seems to be more effective than sleeping pills. The sound through the voltage of the phone becomes an electronic spell of hypnosis.
