help. just started taking my sugar levels earlier this week and on the whole they've been fine however, this morning and yesterday morning my readings first thing were 5.2 and 5.3 respectively BUT after having the same thing for breakfast both days - 2 slices of toast (granary), cup of milky coffee and a small bowl of kellogs crunchy nut cereal my 2 hour readings were 6.7 yesterday and 14.6 today, they're now down to 6 and 5.6 but why such a huge jump today? Thanks of a the responses i've had to other questions, it's been very helpful.
