I answer between TICA lines PQ your message has been revealing 
It happened to me for a year, that did not do the digestion well.I went to the doctor and came out crying because little and more and told me that I was going to die in a little years.I blame all diabetes and gave me a gastric protector (all this without a single test, only heard the word diabetes)
 The usual discrimination to me too 
I went to the endocrine and told him all this (he told me to put a claim against the doctor) and send me various tests and a celiac analysis (they have done you? It was convinced that it would be positive, but no, I am not celiac).
 I am not celiac or intolerant to most food
They gave me some pills, that I do not remember, that I had to take them an hour before eating and eating soft, mixing little and slowly and controlling the hypos/hyper.
 Tell me which please 
The day I have broken sugar, I find it a lot to do the digestion, but because of the reluctance that the hypes/hypes leave me.
 idem 
And about breakfast, I also have the Dexcom and I have also drove it crazy.
Have you claimed Dexcom?It is blocked every morning.So to traffic the coffee and bread beggar in the morning I need as little 3x6 = 18 punctures (sometimes changes are in less than 10 minutes )
In my case I woke up at 80 and without doing anything: neither eat, nor stress put me at 200.
 idem 
If it was a weekend I went up when I got up, that I could several two, three hours.
 idem 
My solution was to have two basal (work days, weekends) and an hour before getting up I wear 1.5 more basal.
 I already have that pattern designed (for myself) 
Breakfast somewhat with fiber and low glycemic index.
 What?I don't have anything 
The bread only goes up a lot, put some olive oil or something that delay absorption.
 What?The bread with oil rises the same 
And eating less of those necessary is not a good idea because the ketone bodies that also affect the stomach will appear
 I already have ketone groups and they are not removed 
Thank you so much.I am expectant to your response and those of others of course.
