suffering from PTSD from multiple military deployments.. have memory loss, Traumatic Brain injury, etc. Suffer from panic attacks and mild depression. Trying to get my dr. to realize my panic attacks are acute and not long lasting; he tries to treat me long term... I need something that I can take when I feel the onset of an attack of an attack much like I take my Sumatriptan at onset of migraine which happens frequently. I want Diazepam or Lorazepam but they are hesitant to give it to me. My dentist gives me a couple of diazepam prior to dental procedures so I have tried it before. I am being treated by VA hostpital. Advice?
