I think benzos can be fun. However the fun is subjective; some people say drinking is fun, but I can attest for myself I get zero enjoyment out of drinking alcohol and in fact it probably decreases the euphoria of other substances I normally use.
I don't think lorazepam is particularly fun though, I use it more as a tool than anything. If I need to sit still for 6 hours, like for a class (yes, I have had a college class that lasted 6 hours long, with a 20 minute break in the middle), then 1mg of lorazepam is perfect for me to be able to learn effectively and not have extreme restlessness by the second half of the class.
I would save lorazepam for something useful. That's just my 2 cents.
