anxiety
"The doctors put my dad who is 95 on Lorazepam  because of anxiety but it takes a long time to get in the system, he takes 2 a day and has been for about 8 months and it does not help, if given right at the start of an anxiety attack it takes over an hour to work and then it hardly works at all, and as he has 2 a day you would think it would keep him from having anxiety or at least make it more mild."
