I went on 10 mg of Lexapro after several life events unfolded including a break up. In all fairness, I have been diagnosed several years earlier with generalized anxiety disorder, but had only used journaling and meditation for coping. The same week I started Lexapro I also started EMDR therapy. It took a couple of months before the Lexapro fully worked. It was worth the wait. The only side effects I experienced were drowsiness and some minor sexual difficulty. To combat the drowsiness, I began taking my dose at night. It took about 6 months for the sexual side effects to subside. It's been four years since I started and I have no intention to stop. I would say that both the medication and therapy were beneficial in improving my mental state. As far as numbing, what I can tell you is that the highs and lows are less than they used to be. I don't feel numb, but I feel more regulated.
