Some time ago, my surgery tried to organise my items so that they are prescribed on a regular basis, for my convenience.
I pointed out this makes no sense for my prescription as my insulin dose varies according to what I eat and how I exercise, my test strip usage varies according to how often I eat, drive and exercise, and my syringes and cartridges are for back up so I have no clue when I will need them.
I think this put me in the "too difficult" box and as a result, I order my supplies as and when I want. If I go on holiday for a month, I can order supplies within 3 days of each other; when I come home, it may be six to eight weeks before I order again.
I believe any doctor trying to make type 1 medication ordered at a constant frequency, does not understand what they are prescribing and how it will be used.
