I have been taking Celexa for about 1 1/2 years now. I have not been myself for the last 4-5 months, crying easily, tempermental, foggy, tired, exhausted. I decided I couldn't live like this anymore, it was effecting my life, my relationships, my kids, my job so I decided to quit taking them. Now I'm having withdrawal symptoms. I'm extremely angry, exhausted, dizzy, nausea, numb feeling, how long with this last. I did not taper off the drugs, I just stopped cold turkey about 5 days ago.
