Everyone is different, of course. But I stopped Trazadone after not being able to find a dosage that didn't give me a heavy hangover effect in the morning.

Possibly taking the Lexapro in the morning would work? When I was on that briefly, I was told that if it made me more alert to take it in the morning, but if it made me drowsy to take it in the evening. So maybe you could adjust the time you take the Lexapro according to how it affects you.
