Benzodiazepines are not drugs to be used recreationally, they will bite you in the ass with excessive usage. For instance if you are not anxiety prone already, excessive overuse of BZDs can lead to you developing an anxiety/panic disorder especially if you end up in withdrawals.
It's a bit of a double edged sword that BZDs are very "selective" drugs - by that I mean they essentially only target one type of receptor in your brain (benzodiazepine site on GABA-A receptors). What that means is they aren't anywhere near as recreational as something like ethanol (which is rather nonselective, not only a GABA-A agonist but also GABA-B agonist, dopamine reuptake inhibitor, NMDA/ion channel blocker, etc). But at the same time, they have a tendency to have much less in the way of side effects than less selective drugs (e.g. people can take Ativan as an anti-anxiety aid and still function - you couldn't do that with something like phenobarbital or chloral hydrate) So if you are expecting a similar high to getting sloshed, you will probably be disappointed taking benzos. Even if you increase the dosage, you're then going to risk blacking out if you don't know your limit, and that's a good way to end up hurting yourself somehow, or ending up arrested because of erratic behaviour in poublic, or being taken to the hospital because someone thinks you had a stroke...
BZD's are really better used as tools, than as toys, I say. It doesn't hurt to hold onto some especially if you dabble with psychedelics, 'cause they can be used to help ease bad trips, for instance. Or they can be useful on stimulant comedowns too. But I think eating just BZDs and expecting to have a good time is not going to please you.
(It's not a good idea to mix multiple depressants either, so don't go combining benzos and alcohol or benzos and opioids to "intensify" the high... not only is it an inherently risky act, ancedotes say that benzo usage will actually dull some of the euphoria, or so some people tell me)
