I take Lexapro. Your doc was smart to start you on half tab for a week and then go to full tab. You are likely to avoid side affects that way. I did not experience any side affects with lexapro. It is said to work a bit faster than some of the others, but still takes some time. These SSRI's work by stopping your brain from 'spilling' seratonin. Be keeping more of the seratonin (which you get from light and exercise) your brain should begin to function more rationally. This is why it takes a while for these to work. Your body needs to accumulate enough of the seratonin to help.
I hope this helps. Keep posting Sober . . .
