2 part question...

Which of the following drugs would produce the greatest sense of
"euphoria" and what doses would one take?
1)  co-codemal :  60mg
2)  Xanax
3)  Valium
4) Darvone

Could one use alternative medicines that are non narcotic to produce
the same results?

Two quick thoughts here. Xanax is a depressant used against anxiety
attacks, so I doubt it would produce any euphoria. But more
importantly, synthetic stimulants are dangerous drugs that few people
should take on prescription, never mind for recreational purposes. If
you want natural stimulation, why not drink a pot of black tea or a
quadruple espresso? Better yet, why not ride your bike up a hill and
fly down the other side? Or why not go to the skating rink, or put on
some loud music in your basement and dance like a dervish? That's what
I call euphoria.

All the drugs that you've listed are prescription drugs. Any physician
who prescribed such drugs solely as euphoriants would probably be
placing his medical license in jeopardy.

I wholeheartedly agree with leapinglizard: these drugs are not a
suitable way to achieve a good feeling. Drugs, at best, can only give
you a brief, cheap imitation of the exhilaration and happiness that
can be achieved through genuine experiences in the real world.

Disclamer: this information is based on experience gathered from
sources legaly perscribed these medications who have experienced the
euphoric "side-effects" as a result of legitamate therapy. This
information is not intended to suggest anyones use/misuse of these
powerfull and dangerous chemicals.

ok. generally euphoria is more often experienced via stimulants wich
act on dopamin and epinephrine/nor-epinephrin receptors. Very well
documented examples of this side-effects in currently perscribed
medications are from adderall(dextro-amphetamine) and Ritalin.

If benzodiazapines(vallium, Xanax) are more wwhat you were talking
about, of the two you mentioned (vallium, xanax) I've heard that Xanax
is more euphoric though shorter acting and less sedating than vallium.
Ativan (lorazapam) is also known to produce some euphoria and is even
less sedating than xanax. The dosages reported to produce euphoria in
Xanax and Attivan are around 2-3 mgs depending on your body mass,
metabolism and any tolerance the patiant may have developed. Vallium
Doseges in the 10-30mg range can be euphoric but it is more heavaly
sedating and euphoria quickly fades to slumber. Klonopin (clonazepam)
is a benzodiazapine that is used to treat spasms and seizures and is
more narcotic in effect than the before mentioned scripts. It can be a
little more sedating than say xanax but it's effects are more likely
to produce euphoria.

Recently i've heard alot of reports of strong euphoric side-effects
from slight overdoses of SOMA (CARISOPRODOL) in the ranges of
700-950+mg. Soma is a muscle relaxer and is more closely related to
narcotic pain relievers than to anti-anxiaty medications. The duration
of the side-effects via soma is around 4-6hrs depending on dose.

Hope this helps.
