Hi. been feeling like i'm hungover (no boozing, honest) since on the AD's. It's only been a few days and my head is thumping. I'm taking escitalopram. Is this normal? I know it does say on the leaflet these symptoms can occur but just wondered when it will settle down? Also, I feel slower in my movements and speech. coudn;t get my words out in college today when the tutor asked me a question.
