I wrote an article about your last paragraph here: http://www.shootuporputup.co.uk/2010/08/the-problem-with-a-cure/. It took ages after going onto the pump not to think “ah, 7.30pm – lantus time!”
If we’re not allowed to wish for “complete cure of diabetes”, I would wish for “100% correct basal rate settings on my pump” for a day. I would then quickly note all the settings down and re-use them the next day when the wish wore off.
