KImber in most cases it is simply an issue of your insurance covering the cost. That is what I encounter. Example-some doc recently wrote for twenty .5mg xanax: to take two or three daily, as needed. That could obiously be gone in 7 days. But the insurance company refused coverage on the refill 11 days later-rule was 30 days. Simple, We called doc, told him and he cancelled orginal refill and wrote another for 90 .25. The insurance people were so pissed, but they had no choice- new prescription and enough meds for a month. The dr just told the patient "You abuse them, fine, but you get no new prescription from me for 30 days. There are all kinds of ways to "screw with the insurance company rules. Just have to be creative.
