Withdrawal is tough. I found with suboxone I was able to go down to the lowest dose when I was pregnant easily enough, but going down to half a pill was too much. I was not able to get off entirely. It’s often the last bit that’s the hardest. With Benzos I. Sure you know you can’t quit cold turkey or you risk death. Tension and anxiety may last for weeks, I’m afraid. The worst part will be the first week. But once you’re off completely you will experience a lot of anxiety for an indeterminate amount of time. Depends on how long you were taking them and just how physically addicted you are. I’ve never been addicted to benzo but I’ve been hooked on heroin and the panic attacks lasted years.
