I've been taking Lexapro 5-10mg (liquid) for 3 years now. The doctor told me to stop it by the end of January. When I reduced it to 5mg from 10mg, I had horrible tremors and headaches. Now I'm quitting it completely and so far I've had no appetite and horrible nausea. I'm taking 4.5mg and the symptoms have already started. How long does the nausea last and how can I make it not as bad?
