Hey, Bisco! So great to hear it's been improving for you. Step by step and you'll get there.

As for the Ativan, it could be several things; the really likely would be that you're suffering from tolerance withdrawal I think. But there's always a possibility your body is simply not tolerating benzo well, or it's some nocebo effect going on. When you feel ready and when you start your tapering it (very slowly), it will become more obvious which one it might be. The most important thing is you've had this considerable improvement recently. That is fantastic news.

Ps Have the sinus problems cleared up for you?
