Ok, I'm currently taking Citalopram 20mg once a day. I started on this medication about a week ago. I have noticed that for the last couple of days I have been excessively yawning and I looked it up and it said there are some health problems that cause it. Now I am super worried. Can my depression medication cause this excessive yawing, or should I worry? Please, anyone, more information would be greatly appreciated. Thanks in advance.
