I often use the square wave bolus, similarly to Tony.  As giving it over
30 - 60 mins usually suits me, I've never had the problem that John
describes (I've never been a pudding person anyway...), but would be
interested to know if the 508 programme can cope with this - I've not tried
it out.

The reason you were in hospital is important.   A few years back (but not so
long ago that things might have changed...), I was in hospital for elective
surgery.  At that time I was using multiple injection therapy, but the meals
for the day before had been carefully arranged to contain no CHO
whatsoever...("she's diabetic, she can't eat that").  I also had IV insulin
on the day of the op to control bgs - this used to be a standard practice,
and I doubt that things have changed with the possible exception of
hospitals with pump expertise. Even in the latter case, surgery does involve
a stress which would have to be allowed for in the pump programme, and this
might not be acceptable to the surgeon - IV insulin acts more quickly and so
is more readily controllable (if anyone checks the bg...).

Tony, I agree, and I think it's insulting to people who probably know a lot
more about their condition than those treating them when these attitudes
prevail.  Unfortunately, few medics know much about diabetes, let alone
specialist subjects such as pumps - a few discreet surveys by the medics in
this family support this view...- doesn't make it better, I know.

If your daily basal rates change substantially from hour to hour, you might
need to take this into consideration - but as the change is only one hour
you could simply change your pump time, perhaps when you got up on Sunday
morning (there's no need for the change to occur at 2 am!), check and adjust
later if necessary. Your body clock will get used to things after a day or
two with a single hour's change.  In practice, you probably don't need to do
anything at all (I haven't, although I admit my experience is limited to
this year's changes, but I do fly quite a bit and even then only need to
adjust if the change is more than three or four hours).
