What is the likely weight gain if taking mirtazapine and how soon will this happen. thank you ?

It differs.: Mirtazapine is an atypical antidepressant that can stimulate appetite when given in lower doses, improve sleep at higher dosages. With improved appetite, weight gain is expected and it can happen as early as a week. Weight gain differs.

It happens: But in my experience, not to the degree that people write in about. Could be quick, or insidious not a major problem , since med can be stopped with no major problems from it.
