Where are you going to get secobarbital from??? That's an extremely rare drug nowadays... Mandrax (methaqualone) is actually easier to get hold of.
The closest thing to Seconal would probably be Soma (carisoprodol). It's a powerful muscle relaxant and a prodrug to meprobamate; an old school sedative of the carbamate variety that basically works like a short-acting barbiturate but with a better safety profile. It's VERY strong shit... feels like GHB but with a lot more muscle relaxation.
