And let me preface this by saying that I have gone cold turkey from hydrocodone
more times than I wish to remember--and I've survived each time thinking the physical symptoms weren't so awful. So I am no stranger to the discomfort of withdrawal. Anyway, with the Effexor withdrawal, I was extremely lightheaded. Very nauseous. And I even experienced vertigo, from a sitting position. I don't normally feel vertigo--sitting, standing, climbing--whatever. It was really disturbing.
