Question about Benzodiazepines on DPD

Hi guys,

i recently got some benzopills from my psychiatrist for trying them out on dpd(did not tried them out yet).

i actually asked for some lorazepam because i heard they are prescribed as pills aganst panic attacks and hence might effect on dpd...

i got some some lormetazepam pills instead.... and found that they are mostly prescribed for insomnia and as sleeping aid(maybe not used in US).... my general question is merely, if all benzos are working the same?? just the dose and duration of effect is different, or do they actually have a noticible different effect? if someone knows more about that i would appreciatean comment,

Thanks Guys!
