shit, don't you have tolerance to anything like alcohol, GHB, phenibut or something? those would be cross-tolerant
aside from that, 1050mg is a pretty big dose. i'm kind of a lightweight when carisoprodol is the drug, and 1050mg and i'm a total mess. most people would agree that dose SHOULD do something. i know i can feel the effects from 750mg in 20-30 minutes, and that's enough of a dose for me.
though, perhaps most of the effects from carisoprodol are from meprobamate (its metabolite) and perhaps you lack the enzyme necessary for this metabolic pathway? idk if thats even possible, just a wild guess.
well seeing as your post was over an hour ago i guess that either you didnt feel anything or took more and passed the f out lol
its a shame anyway man, carisoprodol is a very fun downer
