Hoo boy, I know a lot about this topic. I was prescribed klonopin for anxiety and insomnia way back when (cheating spouse and 2 little kids). Much later in my life, I was told it was intended only for very short term use (6 weeks max) and I was prescribed through my PCP for 25 YEARS!!! In 2018, I moved to another state and found a doctor who agreed to help me get off of it which is very hard to do - it took me a year. Not only does it call brain fog, but it causes memory loss and long-term use of benzodiazepines may increase the risk of developing dementia by 32% to 84%. I was so relaxed while on it and slept like a baby and I'm sorry it was EVER prescribed to me.
