I quit taking my EFFEXOR XR 150 MG this Sunday. I drove in to the drive, still in my car, held my wife\'s hand and told her I loved her and the children and if not for them, I just wanted to go to sleep and not wake up. I then considered the EFFEXOR was causing this series of thoughts and manic depression, so I quit. I have been crying since. I feel brain shocks that run down through my arms and legs. If I move my eyes quickly, I have to remember to breathe. I feel a panic set in, my vision is constantly blurring and I am checking my pulse numerous times daily. When these feelings occur, it sounds like my hearing shuts off and on between my ears and it is almost like I can hear some sort of charge or movement of sorts between my ear drums. My dreams this week have been strange to say the least. My hands shake, I feel these almost electric likecharges running through my body and I am asking myself, is this addiction? Does the medical community understand what they are doing when they prescribe this drug and why don\'t they tell us what could happen? They seem to hand it out like candy. You must have a chemical imbalance, here, take this and you\'ll feel better. Help me undersand how they determine a level of chemical imbalance before these medications are prescribed. What tests are done to determine doses? Where do I go from here?
