I have taken several benzodiazepines, such as alprazolam, lorazepam and diazepam but never have I taken meprobamate. Meprobamate isn't a benzodiazepine, but I've read that the effects are similar. The popular muscle-relaxant carisprodol (brand name Soma) metabolizes into meprobamate, so the two drugs are essentially the same. Has anyone ever been prescribed to meprobamate or carisprodol, or at least taken it once before? If so, what are the general subjective effects, how long do they last, and how are the effects similar to the general feel of the benzodiazepines? Also can anyone could compare meprobamate/carisporodol to the effects of an intermediate-acting barbiturate, if not any of the benzo's?
