"i started a course of lexapro around eight months ago. i suffer from major depression so i started out using 5mg, then up to 10mg and then 20mg. at first i felt a slight feeling of nausea that only lasted a few minutes. the other side effects i experienced were slight mania and decreased appetite. it helped me remain calm during pressure at work. i am now weening off escitalopram and am experiencing involuntary muscle contractions whilst entering sleep beyond r.e.m. i also find myself chomping my jaw sometimes and am having cold and flu symptoms along with an unusual head rush that left me a little bit disorientated. i am on my final days of escitalopram now, and i&#039;m sure side effects will diminish soon."
