I take 112.5mg of venlafaxine (effexor) every morning. I ran out on Friday and cant get my prescription until tomorrow because my doctor is gone. I am suffering severe withdrawal - nausea and vomting, out of body experiences, +++ anxiety and depression (crying), I feel like I'm dreaming and not really here, dizzy, unsteady.... how long after I take my dose tomorrow will these symptoms subside?
