I have been taking Klonopin for 20 years for panic attacks and anxiety. The dosage has steadily increased to 2mg three to four times daily. I am going to be admitted into a hospital in the next day or so to be weaned off this drug as my doctor feels this is dangerous, and my anxiety has returned meaning that I have developed a very high tolerance to the point that it is no longer effective, but physically I need the drug. However I have heard that it completely re-wires your brain. I am worried about having seizures, and not feeling 'normal' again. I would appreciate any help with my concerns.
