The basic technique is to space out the pills
you take in a consistent manner until
you take only one at night, then half at night and then none.You can try asking a physician to prescribe you some Requip for restless legs, Neurontin for overall distress, Clonidine for blood pressure and general anxiety control and maybe get some over the counter Valerian for sleep and sedation.
But, seriously, you must be completely committed to the goal of quitting.
