I was on sertraline months ago and stopped taking it because i felt good now i am back on it the 50 mg dosage its been maybe two weeks or so. I've noticed that im still anxious and have the spacey brain fog feeling and i cant sleep that well and my pupils look dilated.. not sure if that's from the constant panic attacks or not.. feels like my pupils twitch .. has anyone had this happen to them before ? i hope it gets better ugh anxiety and depression suck
