Hi What you experience when you come off quickly is withdrawals they mimic anxiety/depression. I went cold turkey off effexor not an easy ride i was on 150 mg's for nine years, I am still having sleep disturbance. I'm getting a life back i'm not tired all the time my anxiety has gone. We go on these drugs for anxiety but after a while they cause more anxiety. Contact CITA my support group they will tell you how to withdraw slowly over months GP's do it too quickly you need to beable to function whilst doing it, they are on the web. Remember it is not as easy ride
these drugs have damaged our bodies but it is well worth it, the first 12 months is convalescence.
Take care and Good Luck with patience, support and being kind to you, you can get your life back !!
