I've always taken ZOLOFT (on & off) in the past (6+ years) and ultimately go off due to weight gain. Of course, my Panic and Anxiety returns, along with many other symptoms - dizzy, tremor, severe worry, etc... So, I though I'd give Lexapro a try. I've been taking for only 3 days and feel just horrible. 5mg - feel nausea, gagging, anxious, panicky, chest pain +++. I don't remember ever having these on Zoloft. Can or should I just switch to Zoloft seeing I've only been taking it for three days? I can't go another day like this.... thanks for any help.
