Hello, I have a history of depression and anxiety. I have been taking Zoloft for this for almost two years. Recently, I have been experiencing an odd sensation that has gone from occurring once a week to every single day, many times a day. The sensation is almost like I am high, or dreaming. Sometimes this feeling is accompanied with palpitations. This sensation can happen all on it s own for no known reason, but I have noticed that it does tend to occur when I move my eyes or head. The occurrences are brief and last maybe 1 second, but are extremely frequent as of late. I do not experience ringing in my ears, I have not had a sinus infection recently, and I have not been fainting. I do not believe this to be a side effect of the medication, but a side effect of my anxiety/depression itself. Is this possible? Is there a term for what I am currently experiencing.
