Started for a week on Lexapro at 5mg.
I'm also on 0.50mg Xanax 4x a day.

The second week I went to 10mg of Lexapro..
Now I'm just past 3 weeks and I find that:

1. The Xanax isn't working as well. Although my HR stays in normal range the feeling of 'doom' death and anxiety are always present
2. I get small palpitations (single ectopics) every half hour or so.

I know that Lexapro can cause increased anxiety the first few weeks.. Could it be increasing the GAD to the point that my Xanax isn't functioning as well? Additionaly has anyone else had palps on it?

I want to stay on it, I've read that a lot of people quit because of the initial increase in anxiety. Also, I don't want to increase my dose of Xanax becuase it's harder to come off it later.

Advice?

Also - no real other side effects.
The first week I felt dizzy often, to the point I questioned riding my motorbike at times.
And I had intermittent diarrhea which sucked.
