For me it was significantly "messier" than any benzo I've ever tried, by which I mean, loss of balance, muscle weakness, general clumsiness. Cognitively, kinda nice and relaxing but also kinda unremarkable, not any better than a mid to heavier dose of diazepam, for example, but actually I also thought it was also far less likely to induce the kind of paradoxically manic sobriety delusion that most benzos can, to a greater or lesser extent. Perhaps this was exactly because of the obvious physical clumsiness, or perhaps barbiturates aren't quite as likely to induce sobriety delusions in general, I haven't tried any others so wouldn't really know. The physical clumsiness I'd say was more pronounced to the point of being out of step with the cognitive effects, since if I was just sitting down I could forget that I was so impaired, and then I'd stand up and just immediately fall over, for example... stupid shit like that. I guess this is kinda opposite to benzos where the cognitive spangledness often is out of step with physical impairment, hence sobriety delusions and weird behaviour. For comparison, I think I'd put alcohol between the 2 of them as the kinda yardstick GABAergic substance where the cognitive impairment and physical impairment are fairly well entwined.
