I have been taking Brintellix for several months now and I am at the highest dose. However, I am still physically tense and my mind races at times making it hard for me to concentrate and fall asleep. Sometimes I find myself clenching my fists or gritting my teeth and I get very anxious driving or being out in public in large crowds. I am seriously considering asking my doctor about putting me on Klonopin but one of my downfalls is that I have little to no patience so I want it to work the first time. I have done extensive reading on Klonopin, Xanax, Valium and Ativan and everyone seems to agree that Klonopin is the winner. I would just like some input from anyone who is or has been on it to tell me what they think. Thanks!!
