NIGHT TERRORS FROM THIS DRUG! I was on it over 2 years and put up with it. I was afraid to withdraw because of the horror stories, but finally I couldn't take the nightmares and vivid dreams anymore, and I withdrew myself slowly. I have been off it one month now and I feel so much better. I asked people why I didn't get the horrible withdrawal effects and was told probably because I was on other drugs. (I take Depakote for Bipolar, and I purposely took Valium while I withdrew from the Effexor).
