Been on zoloft for 4 weeks, initially 50mg and in last 4 days 100mg, before that I was on Cipramil 60mg. However, I have had terrible anxiety attacks in the past few days, zero motivation, rapid mood swings and the agoraphobia that has been dormant for sometime is creeping back. It is a long time since I felt this bad. Am I being impatient? Is there a possibility I am on too high a dose? I am going through major stress too right now so need to factor this in. Thanks.
