I have been on Effexor before and I don't remember if I had this problem before, but in the last couple of days I get weird images/thoughts that come into my head, It scares me and I panic. I called my PDR and she says that it is not a side effect of the effexor. She said that she can take me off slowly of the Effexor, but I am so scared of the withdrawals. Has anyone else had this problem? I know I'm not crazy.
