I started Celexa about a year ago. I went from 20 mg to 40 mg to 60 eventually. I was on 60 from February to October, dropped down to 40 about mid-October then for about a month, then dropped down to 20 for a week, took 10 mg for 2 days, and today I stopped taking them altogether. Do you think I'm going to get sick? I have been shaky and overwhelmed at times, other than that no major symptoms.
