I was on Effexor for several months ago for depression after not responding to other meds very well. When I went on Effexor I was all energy; bouncing-off-the-walls energy! I had to get prescription sleep aids to calm down at night. I also had insane dreams! They were incredibly vivid and bizzare. They were almost every night too which is very strange for me. The dreams are what I remember most about the drug. Although it definately got rid of my depression the withdrawl was just as horrible as everyone said it is. Hope this helps someone.
