I checked in to Glenbeigh rehab , they call a hospital, last April. I had been prescribed 1.5 mg.of xanax a day for 24 years and was abruptly cut off then oct my GP abruptly discontinued effexor. The post accute withdrawal was the worst experience of my life. no need to go into all of consequences of PAWS those who have experienced it know. with the help of an amazing psychiatrist who had been thru effexor withdrawals herself, i’m doing better. still have bas days but i’m becoming me again. You need to seek help from a good psychiatrist trained in drug withdrawal. there is help. 4 years is too long to suffer
