Valium is usually prescribed because it can help you sleep and it does cut panic attack symptoms. That’s the only reason.
I would say that using valium as a sleep aid is extremely risky.
You do not want to rely on pills to assist you in every day functions at all, because to become addicted to pills, most especially benzodiazepines, is truly Hell.
With regard to panic attacks, I never even believed in these to be honest. They sounded like BS to me. However, I certainly experienced them after suffering a heart attack.
I would describe the ones I had as a very sudden onset extreme fear of imminent death that resulted in shortness of breath and very rapid heartbeat. After just experiencing a heart attack, the rapid heartbeat was not welcome at all.
However, even though I did have a prescription for valium for those attacks, I used as little of it as I possibly could, and tried to address my mindset thinking that was the cause of the attacks, rather than addressing the symptoms with the pill.
I am very glad I did this, because I know valium is extremely physically addictive. I already beat an addiction to xanax earlier in my life, and I did not want to be exposed to this class of drugs again knowing how easy dependence on them can form.
