1. A method for the treatment of psychological dependence on methamphetamine in a human patient having psychological dependence on methamphetamine, wherein the patient is not undergoing withdrawal, comprising the sequential steps of: optionally administering about 50 mg of hydroxyzine to the patient; administering to the patient a therapeutically effective amount of a composition comprising flumazenil in a pharmaceutically acceptable carrier, wherein the therapeutically effective amount of flumazenil is between about 0.5 and about 10 mg/day; and, administering gabapentin to the patient in an amount of about 300 mg to about 600 mg.
2. The method of claim 1 , further comprising:
evaluating the patient via a pre-treatment regimen;
monitoring the patient during treatment;

5. The method of claim 2 wherein the outpatient regimen includes at least one of diet, exercise, cognitive therapy, or providing a pharmaceutical composition.
6. The method of claim 5 wherein the pharmaceutical composition includes at least one of hydroxyzine, glutamine, fortified vitamin B complex, or an amino acid supplement.
7. The method of claim 2 wherein the steps of administering a therapeutically effective amount of the composition comprising flumazenil in the pharmaceutically acceptable carrier to the patient; monitoring the patient during treatment; and prescribing the patient the therapeutic compound in addition to the flumazenil, are repeated three weeks after initial treatment.
