somas aren't good recreational drugs imo. the main psychological effects i got(even with large doses) was moderate drowsiness, apathy/feeling dull and bored, slowed thinking and cognition(and not in a "fun" way), and mild depression.
even though it is a GABAergic, it didn't provide pleasant effects that benzos, barbs, alcohol, and even it's "big brother" meprobamate give(lowered inhibitions, talkative/social mood, euphoria, relaxed/content feeling, etc.)
however: somas are good muscle relaxants and kill pain pretty well. this makes them useful(for me) mixed with benzos on comedowns to help relax tense muscles or with opiates to boost their pain killing effects.
when i need relief from pain, i can pop a couple somas with a weaker opiate like codeine(tylenol 3 60mg., which also has tylenol in it) and get effective pain relief more so than the tylenol 3's alone.
