Sleeping problems


Hello everyone :)

Is there anyone who is struggling with sleep? My boyfriend has a sleeping problem. He is sleeping max 4 hours during the night; sometimes he does not sleep for a few days or sleeps for 1 hour during the night. GP gave him sleeping pills from which he can sleep for up to 3 hours, but when he wake up he feels dizzy and weak. Does any of you know some kind of natural ingredient (which is legal 🤣) or something that could help?
