"i have suffered with anxiety and panic for years, since about 14 y/o. i have tried several different benzodiazepines over the years but always go back to diazepam. i can use it for both preventing a panic attack before a specific situation, or use it to relieve one once it&#039;s started. you can even take it the night before a specific event for nervous insomnia. diazepam calms me down without tiredness or feeling spaced out."
