I have been taking Xanax and other benzos off and on for 20+years and there have been occasions when I have taken 5,6 even 10 mg at once for a week or so I even took 30 mg of Xanax and had to go to the hospital but I was aware of everything and awake with iv in my arm. I have a super high tolerance for benzos. In the last year I have been doing some research on benzos and some testing said you can get Alzheimer s and dementia from benzos then there are tests that say you can t get no such effects from benzos.now I m so scared that I m going to get one of these diseases. I haven t really forgotten anything I have had some minor memory issues in the past. But sometimes I will look at something or someone that s familiar and it s like its/they are unfamiliar. I have been told it is dissociative disorder but I m super super scary nervous and anxious all the time. Even words look weird sometimes. I was diagnosed 20 years ago with a severe panic disorder agoraphobia OCD tendencies. What is wrong with me??????? . My name is James
