Fbg should be taken as soon as you wake up before anything to drink,eat or meds. I reach for my phone and scan my Libre while still lying in bed. I also keep my kit on my bedside table and do a finger test just to confirm before my feet hit the floor. This gives me my true fasting reading. It's also best if you haven't eaten for at least 8 hours and have slept for 6-8hrs. I usually wake-up a couple times a night but get 8hrs total and my doc said this is still ok for a true fbg number.

Get out of bed (5:50), hit the washroom to get rid of last nights coffee, get dressed (shower before bed) and then "test" before anything else - no more than 10 minutes from "waking up" - your fasting sugar continues to climb until you eat breakfast.

And the more you move around, expend energy - even simply getting out of bed (called "foot to floor" phenomena) causes the release of "more hepatic sugars" stored in the liver.

Put on the kettle, take my BP/Cholesterol meds, put on my watch and Medic Alert necklace, get breakfast together and start my "meal timer" (I eat 4 meals a day at 4 hour intervals - give or take 30 minutes - based on when I eat my first meal).

Even on "non-work days" I eat breakfast within the first hour of waking - you have to break the fasting cycle or your numbers will continue to climb.

If your fasting number is jacked up a bit it is still super important to "eat at least 15 carbs" - that shuts off the liver and turns on the insulin - waiting to eat just jacks your numbers "worse".

(that last note only applies to us Type 2's - you are excluded from that Nan) :)

I wake up (if I have a Libre I scan it) then go to washroom, then go back to bedroom and get dressed. Take my morning medications, 3 of them need to be empty stomach and eat 1 hr later (if too hungry can eat 30 min later). The 3 empty stomach fasting ones are Vit D, Domperidone (motilium), Nexium. I sometimes go back to bed if still tired as I only sleep 2 to 4 hrs winter time due to my autoimmune diseases, so the time I have to wait to eat I at times nap so to speak.

When I wear a Libre I scan before getting out of bed and like this morning I was at 5.5, get up to washroom, come back to bedroom I was up to 6.3, by the time I wait the prescribed time to eat I recheck and was up to 7.8 today, so that 1 hour wait time I have to do due to medications really jacks my numbers up at times.

This morning I had "foot to floor" going from 5.5 to 6.3 in 2 min time and then shot right up to 7.8 and this within the 1 hr of being up, so as @A DiabetesTeam Member stated if you can eat within that 1 hr of being awake it would be better to do so, unfortunately my medications waiting time often jack my numbers up, but after eating breakfast by the time my next meal comes around I am often below my true fbs which is right before eating, not the one I woke up to prior to going about my day.

I also reviewed my Libre graph and it appears that before I woke up (phone call woke me up 1 hr prior to my usual wake up time), my sugar level was around 4.0, went back to bed and woke up to 5.5, so might have had the "Somogyi effect" going on when I woke up 1 hr earlier then usual, then foot to floor kicked in also, really not helping my numbers this morning. It is good to wear a CGM to be able to see in real time how fast numbers can go up within that 1 hr of being awake. It can help doctors prescribe the right medication required. Since I had Covid in Jan seems my fbs are up and down, was back to normal this past week and yesterday was 7.9, today 7.8, but this is after the 1 hr wait time from medications as the fast was not broken.

Hope this can help understand the importance of eating breakfast (breakfast = break fast) when you wake up, unless like me you have no choice to wait. Hence why I do not worry much about my fbs as I know it will be down within 3 hrs and stays down the rest of the day so that my daily average sugar levels are in the right range, but this is how my diabetes works because I do not have diabetic medications. If someone is on medications having these numbers then they might need to be adjusted.

A Diabete...

I get up, go into the bathroom. Give my cat a treat(he insists), take my meds. Go into the kitchen feed cat soft food, feed dog soft food with his meds, feed guinea pig. Then i take my fasting sugars look on this site then make breakfast.
Wednesday i add taking cleaning guinea pig cage and kitty litter and taking out the trash before blood sugar and breakfast.

I am on a bit diff routine since I have other meds to take for other issues on an empty stomach n have to wait a few hours after before I eat then when that time comes I test my blood, take my insulin and eat so by this time its usually 11am then i take my vits. So are you saying your running higher sugars when you get up? If so maybe whatever meds your on at bedtime needs to get adjusted to bring your morning blood sugars down? That is possible.....not sure if i was any help or not....Hope it all works out....hugs.....🙂
