Hi. I will start an antidepressant called Selectra, it has sertralin in it. I take it for generalised anxiety. I read that its common side effects are listed as sleepiness and lack of sleepiness at the same time. Do you know how some people get more sleepy and others get less with the same antidepressant? I just wondered because sleepiness is a side effect I would like to avoid because of my finals.
