The most troublesome effect is a feeling of, well, of NO feelings. I feel like a
zombie = no feelings of sadness or joy, no lows or highs, to the extent that I wonder if I've lost my capacity to feel emotions anymore.
I tried weaning myself off of Lexapro and the side effects have been horrifying. Brain zaps, crying spells, mood swings, insomnia (which, by the way, I experienced while taking Lexapro), stomach ailments, etc.
