I cannot imagine why you would take an antidepressant for sleep. They are stimulating, and even if they also have sedative effects, the sleep quality isn't very good. Amitriptyline caused me damage. The first choice is always an antihistamine or a natural remedy such as valeriana. If that doesn't work I can recommend baclofen, codeine or neurontin. All of these can be combined with an antihistamine.
