Alprazolam
"Efficacy never in doubt with this fast acting benzodiazapine. Alprazolam works on the neuro-transmitter GABA to induce calming effects. It is useful to many patients who try it and is preferred over similar medications because of its relative safety. Regardless of how it is used, it is very potent and may be habit forming. A typical dose for a recreational user or someone addicted to this drug may be many times what would be considered safe. If taking Xanax more than 4 mg per day then slowly taper."
