    Reviewed Klonopinon 7/14/2017I take clonzapan at night bcuz I can't fall asleep and stay asleep (often, especially if I only took 1/2 pill at bedtime) like when I wake up and go to the bathroom. I have insomnia, so my brain doesn't shut down. But I will switch it up with gravol (anti-nauseant) so I'm not taking clonzapan every night. Be careful, people can get hooked on this.

    Some hassle
    Reviewed Klonopinon 6/25/2017Sleepiness was an effect, but I gook it only at night for the purpose of easing the anxiety of going to bed and getting to sleep. It worked well. I wish it didn't last as long as sleeping 14 hours could happen and waking up was very VERY difficult. But, I have to admit, once I did get up, I wasn't groggy. (Note: I am also in Adderall) Worst side effect was ED. Just wasn't happening. But for reducing the anxiety that was preventing me from going to bed and getting to sleepitwaseffective

  • Not worth it
    Big hassle
    Reviewed Klonopinon 10/2/2017Really weigh the pros/cons of taking this drug or other benzodiazepine. Do not take long term. I was prescribed this drug for 16 years. It took a few very difficult years to kick the addiction and 10 years to regain mental clarity, but it ruined my physical health. This drug gave me 27 yrs of horrible ear ringing and destroyed my life, my immune system, my career, and my future as a result. It drove me to suicide.
