Lorazepam
"I used to get bad panic attacks, and very severe anxiety, and ativan was the best medication I ever took in terms of completely getting rid of my anxiety. It calmed me down quickly, got rid of my anxiety completely, and made me relaxed and calm. It's very potent and effective. Compared to Xanax I think Xanax works better for regular anxiety and Ativan to me seemed stronger. Also Ativan seemed to considerably elevate my mood compared to Xanax. It's probably best for those occasional severe panic attacks not to be taken too often. Very effective though!"
