I suffer from DP, my rising BG (6.30am) is always higher than the night before, though funily enough not necessarily very much higher, it is usually 6.something. But once I get up my BG continues to rise until breakfast time when it may be 8.somthing. Then when I was following the HCP advice about carbs and eating two rounds of wholemeal toast for breakfast it would rise to double figures, sometimes 12 and stay there unitl 12.00 0r 1.00pm.
I tried not eating after my evening meal, then eating at bedtime, I tried various things, oat biscuits, cheese, peanut butter, on their own or with the oat biscuit. I tried them with cider vinegar. I tried a herb called milk thistle and Chia seeds. but nothing made any difference at all.
I then tried not eating carbs at all in the morning and although my rising BG is still the same, and it does still keep rising unitl I eat, as soon as I eat a breakfast of something like an omelette, my BG will only rise to a normal post meal level of around 8.00 and then start dropping again. So that by 11.00 am I am back in the 6.somethings again.
I hope that makes sense? Basically I have to eat a non-carby breakfast ASAP after getting up and then my BG's behave as they do the rest of the day. But sadly I haven't found a cure for them being higher than when I went to bed.
