If you have taken 1 dosage of Soma (4.2mcg), when it metabolizes, does it metabolize to 23mcg's of meprobamate after a couple of hours. In a blood report if it is listed as 2 different drugs, does it really mean the one dosage of soma broke down to 23 mcg's of meprobamate? After it has broken down in your system, would it be considered a high dose?
