I am so thankful they have something that could stop attacks...I don't know where I would be without it...I got a perscribtion in January for my panic attacks my doc gave me 30 and I have 17 left..the last time I took one was over a month ago..so take it as needed...it's reassuring that it's in my cupboard and if I get them again I have it there. 1mg is what i have and in my early diagnose I couldn't sleep because my mind would race and I took ativan and it would help me sleep a full night without waking....only if I really needed it....can't stress that enough
