anxiety
"I've been taking Lexapro for 2 months now for depression and panic attacks, which seem to come from nowhere (and I've never truly understood how scary a panic attack could be until that moment). It has helped me tremendously! Suddenly this last week the side effects which had seemed to taper, have returned. I have the addition of a headache (which I did not have in the beginning) and irritability. I'm also noticeably more tired than I was before. I am now taking the Lexapro in the evening instead of in the morning to help with sleep - but am curious if it is normal to have the side effects go in waves? It seemed as if they were mostly gone except for the lethargy, now they are increasing."
