As someone with heavy longterm benzo experience, I can attest to having a very bad reaction to Ativan. I have never taken it again, it was a one-and-done, and would absolutely outright refuse and be willing to physically resist and get the fuck out of there if a hospital tried to administer it as part of some procedure. It was that scary of an experience for me. I was heading to dinner and had these prescription Ativan, low dose 0.5's . I took one and wow is all I can say. I felt like I had just lost all hope or that my dog had died an hour earlier. I couldn't even fake it and essentially had to excuse myself.
8 or 9 other benzos have never been able to alter my mood like that. I get terrified even thinking about it even though it was years ago. Everyone is different, most people have no problem.
