Delayed insulin

Hey all if you have read some if my previous posts you will know I have been struggling with my levels after breakfast but only when I'm on my morning shift at work. Today has been no different but instead of just checking at 2 hours I continued to check in 15 minute intervals and only notices my level dropping about 2 1/2 hours after taking my dose. Could it be that I just need to inject a bit longer before my breakfast when I'm up early?

I honestly dont worry about after food spikes (esp early morning - i have DP) as long as your levels are good after 4 hours then DAFNE says your doing it right.

reading Phoenix's article makes me believe I'm wrong please disregard above

Certainly worth a try as a lot of us type 1's find that the timing of insulin injections is important in preventing postprandial spikes, worth mentioning though that you should be careful that you don't go low before you eat as you don't want that happening whilst working!
 
Quite possibly. You need to match the insulin peak up with the glucose peak, so you could try 20-30 mins before you eat. What is it you're having for breakfast?
 
I have oatmeal with some protein powder mixed in and some peanut butter. I weigh everything out to keep it a constant to see how my insulin is effecting my levels. This morning i woke with 12.3, had my insulin and breakfast and 2 hours later I was 15 then about half hour later I had come down to 14 then an hour and a half later I was 11.

Bolusing earlier could work, depends on the type of food you're eating and the level at which you start.
If you are in the 4s or 5s taking your insulin early could be problematic, less so if you are higher.
I came across this yesterday when I was looking for something else.
Strike the spike

Edit Just found an update of the same article which is actually more readable
http://www.diabetesselfmanagement.com/a ... ke-ii/all/

If you follow the links to the PDF (below article) there is a useful table suggesting timings depending on how high your glucose is before the meal and whether the meal is high or low GI.
(note the watch mentioned is no longer made and the postprandial target for adults given is the ADA one (180mg/dl , 10mmol/l) The UK one is a bit lower at 9mmol/l for adults using insulin.
I found this CGM trace interesting The first one was from when the bolus was given at the start of the meals, the second when the bolus was given 15min before it.

I have noticed when my morning levels are lower everything seems to work as they should but when I wake up high and try to correct it's as if the insulin takes a lot longer to work

I have been having similar problems but at lunchtime.
I have been on a pump for 4 months now, and have gradually reduced basals - with basal testing.
But I have also noticed that post prandial lunch problems have been increasing, and recently have linked those 2 factors, as i think ??? that my previously higher basals were supporting my lunch carb ratio. So I have just updated lunch ratio - more insulin.
As you mention some high readings pre meal, I wonder whether either higher readings are raising your insulin resistance on those days, or whether it is a combination basal bolus effect.

PS, I am not sure I have sorted my settings out yet, more testing necessary.... great.
