I have just worked out on carbs and cals that a 120g slice of Christmas cake with the marzipan and icing sugar will be around 120 carbs? Can someone please advise before I do a huge bolus that may make me I'll?
@tnbnate, I would be very reluctant to take a high dose of insulin so close to bed-time, you might spike but come crashing down 2 hours later, if were to have a slice I'd make sure it was a small slice and eaten after a main meal.
