I cannot profess to be an "expert", however -- I know that there are specific uses for each benzo -- and also specific things they should not be used for. There are also some benzos that have multiple uses. I am pretty sure (though obviously I'm not a doctor) that certain ones help more with anxiety (such as alprazolam or clonazepam) than others that are designated for sleep. Clonazepam is also an anti-seizure medication. So benzos have many uses. It seems to me (being a user of prescription alprazolam and clonazepam in distinct moments in my life), that these two are the best for anxiety. Though I know others can help with anxiety as well (such as lorazepam). Also, I'm not sure (though, once again, I'm not your prescriber, obviously) that you want to use two benzos at once. That was told to me once by a doctor (though maybe there are times in which two are necessary). All in all, I'd recommend speaking with your provider about it.
