@kayraymat I think generally the “as needed “ is to be determined an hour or two before bedtime. Are you sleeping at this point and don’t think you will it or amped up and think it will be difficult to sleep

Imo, Trazadone fits into a sleep schedule as an every night ritual for the reason you mentioned. Taking it as needed doesn’t mean one can’t take it every night, especially if on the nights you don’t take it you have insomnia and wind up taking it later
