I think that you may wish to give it a bit more time...like another month. I know that seems forever. I also would talk to the prescribing doc for input.

I used to take lexapro during the day..morning. I took 10 mg and I did get to start 2.5 mg or so in the evenings when life was rough but that extra amount made me a bit sedated. I think it depends on your needs and your therapist/prescribing doc's thoughts for this med. The symptoms take a while to even out and the meds to maximise and generally that can be up to 8 weeks.
