I have been taking Zoloft for four years and its been fine, great for the first three. Recently I've beeen getting more anxious so I'm weaning off of it and trying Lexapro. now at 5 mg and in one week 10 mg. I have bad insomnia with it and alot of anxiety. I have a little nausea but thats fading. Is it normal to feel alot more anxious when starting this med or should I contact my doc? I feel most anxious at night after I take it and in the am.
