Thank you for your question on ehealthforum.com
You are on citalopram which is usually prescribed for depression. Your symptoms are suggestive of depression, but it is also necessary to exclude any neurological problems like epilepsy e.g. petit mal.
Sleep disturbances can happen in neurological disorders in addition to depression. Your condition requires a thorough examination by both neurologist and a physician. Without having the advantage of direct consultation and physical examination, it is hard to put a finger on definite diagnosis of your problem; however depression and epilepsy need to be ruled out. Hope this information is useful. Thank you.
