The first time i got midazolam I had 911 called on me. For me the mad/ anger part came about because I was so unafraid and confident that I didn't take any shit from anybody. In other words, the benzos set of a chain reaction.
Etizolam can make me angry. Not all the time, only sometimes. As well, the day after I use benzos relatively heavily, I get really angry. On most benzos like Xanax, Valium, etc., I don't get angry while on them though.
Getting angry on benzos isn't unheard of but it also isn't "normal". If you are angry only on certain benzos, I'd say try to avoid those ones
Benzos only make me emotional if I am taking too many or drinking alcohol on top of them. I have had benzo addiction and withdrawals in the past and it is really not a good time at all. Nowadays I take Ativan at night and when I need to with little to no negative side effects.
