I recently had my dose of citalopram upped from 20mg to 40mg, have been taking 40mg for 2 weeks now. For about a week I have been experiencing strange feelings such as:

My legs feel really light and it's as if I am floating when I'm walking. I feel as though my body is a robot and I am controlling the robot when I am walking. I look at my hands and they don't seem like my hands, they seem like someone elses. I feel quite unreal. Though my conscience reminds me that I am real.

When I am walking my legs feel so light, I often feel like they are thin twigs that are going to snap when I bend my knees.

I also go off in daydreams a lot of the time and just zone out. Also getting body jumps when I am sitting down or relaxing.

Are these all normal side effects??
