My doctor switched me from 10mg name brand Lexapro to 50mg generic Zoloft 1 week ago because of my insurance. Was on Lexapro 18 months. I'm not doing well the last few days. I'm irritable, obsessively angry at the Heating Man, and feel a major anxiety attack on the way. Should I hang in there a few more weeks, or, alarm my doctor? Thanks, I'm worried, I don't want another episode, it's been a long time.. Scott
