Lexapro and
Celexa are very similar SSRI's the way my Dr put it, it's like one works on left side and one works on right side of same cell. I have taken celexa in varied doses for the last 4 years, initial symptoms were severe body aches, iritibility, shakiness, speed-like high- these symptoms went away after about 14 days. I tried lexapro and had the same effects with slightly less irritability.
hope i helped.
(SSRI= selective seratonin reuptake inhibitor- meaning u have more seratonin running around in your brain, a sign that you have too much seratonin is aggression.)
