I must add I switched from citalopram. I didn't have hardly any side effects from switching but since I upped to 10 mg escitalopram I am getting so tired!! I'm sleeping ok at night but wake up shaky and within an hour of taking the tablet I'm falling back to sleep and still feel like I could sleep now at lunchtime! Is this normal and will it wear off as I can't function for tiredness. It always wears off by mid afternoon and by the evening I'm fine. I also feel flat emotionally. Thanks in advance if you reply.
