Thanks guys,
We had built up a back up supply of a couple of bottles, through him using 1.5 bottles when the rx called for 2. But now his increasing needs are such that we have no backup and definitely no spare bottle to keep at the school. I'd like to rebuild our comfort zone by asking for 1 more bottle per month. What do you think, is this asking too much?
We are comfortable with the few boxes of strips we have left after each month, and like to rotate the stock so they stay fresh.
We have about 5 boxes of lancets

due to his habit of only changing it out for each new vial of strips (the nurse gives him greif about this), but we haven't refilled that prescription for ages. These should last him well through college, maybe that could be called hoarding!
I know there is an option of getting our supplies 3-monthly through mailorder, but I feel more comfortable going to the pharmacy than having insulin sit in the heat out here (Tucson).
