I have been on effexor for two years taking 300 mg a day. I have tried to go off of the drug on my own several times and each time I was determined that this day would be the last day that I would take this medication. Boy was I SO WRONG! First week I only took half my dose and felt sick at my stomach all the time and I always seemed to see things out of the corner of my eye almost like someone walked past me but no one would be there. Then I stopped taking it all together. I just did not want to be dependent on it anymore. I always felt physically sick but mentally seemed to be ok. It was not really bad until after the second day and I felt like my whole body was being shocked. My senses were overloaded. What I looked at, what I touched, what I heard was unbearable all I could do was hide in a dark room with a pillow over my head and pray that I would not have to go and take that pill. If someone spoke I would snap. If someone touched me I felt shocked all over and the flashing in my eyes, almost like I was only seeing things frame to frame or like a stobe light if you know what I mean, just made me think that I was going to die. This has been the worst experience in my life. All I wanted was to get over the loss of my newborn child. Time would have healed the pain and depression from that experience but time only worsens the pain and hell that I am going through taking and trying to get off the drug effexor. And guess what? I had to take that pill!
