Hello. Did you start straight on 20mg of Lexapro or were you on a lower dosage and then it was increased?
Same with Buspar, did you start straight on 10mg three times daily?
Will await further information.
Those are higher starting dosages. I usually start 10mg Lexapro and assess efficacy after about 4 weeks before making further adjustments. Buspar starting dosage is 7.5mg twice daily...I sometimes start a little higher. This may be the issue, that your body is still adjusting to these meds getting into your system.
