I have been on Celexa for about 2.5 months, and have been experiencing really bothersome tremor and muscle jerks/tics since then. It is really intolerable at times. I have had to decrease to about 5mg, which appears to still be effective, but the shaking persists. I have been on Celexa many times in the past (the most recent stint I was taking 40mg for about 3 years), and have never experienced shaking like this. The only change is that I am 4 months postpartum with my first child. Anyone else experience shaking on Celexa?
