Hi Una 
The high morning level could be down to the Dawn Phenomenon where your liver will dump glucose into your bloodstream to help you start the day, so your level goes higher. Sometimes a small carby snack at bedtime can help to stop or slow that down.

Hi Una, what you discribe is extremely frustrating but unfortunately not uncommon, while we sleep our bodies use little energy its as if we were computers and whilst sleeping we shut down certain services to conserve energy, then shortly before we wake our bodies kick into action and release hormones into our blood like plasma cortisol, growth hormone noradrenaline, adrenaline, and glucagon these hormones are released to get us ready to 'face the day' to kick start our bodies into waking up, unfortunately it also has the effect of raising our bg levels.
It is called the dawn phenomenon and is well documented, search the forum or Google you will find lots of information about it.
Edit: you beat me to it Daisy

Hi there all
not hijacking the thread - but this grabbed my attentioned because of my own frustrations with higher morning readings.
I've posted something regarding rising glucose readings at night on the ask a question section - my 'dawn phenomenon' started 1am in the morning (?) last night after I went to bed at 10lnm.
I tried Google, it seems to suggest the liver dumps to compensates for a drop in blood glucose (so more akin to T1 Diabetics) - how does this work for a T2 who has insulin resistance.
I've done some tests in the night, no drops just rising each time - any ideas on this?

I was told that it more like (the comment above) the body getting ready for the morning and probably goes back as far as prehistoric man. You are all fit and fighting and ready to go out and hunt down breakfast and your body has released lots of glucose from the liver. Some people mention having a couple of hob nobs in the evening before bed, I must admit I have one (just one) cube of cadbury's milk chocolate to fool the body a little and make it think it is already a bit stocked up.

Hi - I had 2 squares of 75% dark choc and 2 G&Ts (slim line tonic) last night reading at 8pm was 7.1
Went to bed at 10pm
Woke up 1:10am and reading 7.6
(woke up again but too tired to test)
Woke up officially this morning and tested 8.2
I'm just wondering for a T2 who's already got insulin resistance, would the technique of eating something just before sleeping not make it worse?
Tonight I'm not touching any alcohol - but am sure from exhaustion I'll end up sleeping through the night eh :lol:

The feed back I was given somewhere was that it can fool the body into thinking it alread has some reserves of glucose so not so much is released from the liver....I'm afraid I am a newbie so no guarantees with this

My understanding is that there are two separate phenomena going on here.
The dawn effect applies to us all (type 1 and 2) and has been well explained here as getting us ready for the day. It operates shortly before, or on, waking.
The night effect has a posh name an endocrinologist told me but I've forgotten! That's more to do with night prevention of sugar levels going too low by liver dumping. That applies to type 1's and also type 2's on some meds, but not often type 2's on diet only. Diet-only 2's tend to have a fairly flat (night time blood remains constant) reading and then a rise in the morning.
In my case, diet only, my sugars on immediately waking are about the same as when I go to bed, but within ten mins they're up by 0.5 or more.
I repeat, this is just my understanding!

Malc... I wonder of you are thinking of the Somogyi effect... not something I fully understand either but I found this at dLife...malcysykes1 said:

Pianoman, yes you're right. That's the word the Endo used that i couldn't remember. I read your link, and it explains why that effect (somogyl) doesn't effect diet-only T2's, as oppsosed to Dawn effect which does. I think this answers the earlier queries on this thread.pianoman said:
