Sorry to hear that. I’m trying 20 mg Lexapro. In the past 10 mg worked perfectly, but not this time. Keep waiting to the increase to kick in.. It’s almost 2 weeks on 20 and I don’t see much difference. By the way, a friend takes 100 mg Zoloft (Sertaline), for panic attacks and it works wonderfully for her. I know we are all different, but thought I’d mention it to you.
