i've been taking zoloft for 3 or 4 weeks now, and for the most part i haven't had any side effects. a few mild headaches at first, some nausea in the morning. and yeah it aggravated my acne for 5 or 6 days, but it's clearing up now and the headaches and nausea are mostly gone. i've been trying to work backwards from taking my medication at 1am to the point where i take it at 10pm because i'm about to start school again and will no longer be staying up so late, but tonight i forgot and didn't take it until 1:30am. is that enough of a gap to cause a headache? like, withdrawal? or is the headache i've had for the past few hours unrelated?
