The desvenlafaxine was a step down from effexor. I am weaning now from the effexor with the desvenlafaxine and olanzapine. So far 10 days in I've suffered some minor dizziness. Today I start the lowest dosage off desvenlafaxine. I'll take for 1 week along with the help from 5mg of the olanzapine. Then stop the desvenlafaxine. I'll be. Off the snri from hell. Never again! Then start with 20 MG of Prozac a ssri. So in 3 weeks I've have gotten off effexor and klonopin. I have to stay on the 5mg olanzapine and 20 MG Prozac because I'm still a sufferer of depression and anxiety. See how this works. Overall I haven't suffered any of the withdrawals others have suffered. Was on 3mg of klonopin and 300 MG of effexor. Good bye to both!!!!
