I have a depression that I am taking Effexor (XR), Seroquel (XR), and Clonazepam to treat. During panic-attacks, I am prescribed the occasional Lorazepam (Ativan) or sometimes even Diazepam (Valium,etc.) They make me become a zombie and go to sleep with no worries. I haven t slept in over 40 hours, and I ve taken a stimulant (def ain t pepsi) to keep me going while I was forced to be awake today, But I am getting panic attacks again (I ve spent the better part of the day crying on the floor and I know the lack of sleep is causing more depression). Is it safe to take one Diazepam to sedate me while I am still on a stimulant?
