Sertaline side effects

I've been taking sertaline for about 30 days. I think it may be causing me to forget things right away. Especially right after I say them. I've had problems with concentrating as well. That is my 2 main concerns. Does anyone feel they have experienced the same thing while on this medicaction?

Yeah my memory is terrible! Especially my short term memory, have you had any other types of side effects?x

Nausea frequently

Dizziness/ light headedness

Fatigue

An empty numb feeling

Confusion at times not horrible but it's there.
