Hi Tammy,I started having panic attacks this year after my surgery,I had a real bad one last week,I went to walmart,so many people,pushing and shoving ,I made up my mind that I was going to get in line and not put my items down and run,I was shaking so bad,that I took a ativan right there in line spilling most of the pills on the floor,after I paid I ran to my truck,and sat there for 5 minutes,just trying to settle down,I am on zolfot,but so far its not been working,but its been only 2 weeks,so I still need the ativan..my heart does the extra beat and then I have the chest pains,my heart Doctor says Im fine...so I am just trying to adjust to this problem,I don't understand what they mean by level 1 2 3 maybe someone will let me know..take care..
