"been on clonazepam for a while. it is not as effective for me as lorazepam since most of my anxiety is due to severe, treatment resistant ocd however it&#039;s still effective in reducing debilitating anxiety. it has a longer half life than lorazepam and xanax but it&#039;s slower to take affect. my doctor combines this with hydroxyzine for panic attacks and it works quite well. i recommend this benzodiazepine over other since xanax has an extremely high chance of dependency, and over lorazepam because its just recently been discovered that lorazepam can cause dementia."
