Hi Riri
I've found that the El Paso kits are worse than other makes.... but maybe biased as the ones sold here in France have partially hydrogenated fats in them.
I think they give an underestimate for the carbs. I would calculate them a bit higher.
Soft flour tortillas themselves contain 19.8 g each (the ones actually called soft flour tortilla wraps are 28!)
The mix contains 35g of 59% is carb; and most of that sugar. So there is 20g carb in the packet. An eight of this is 2.5g.
Therefore the tortilla contains 21.5g carbs before adding the peppers, onion, any salsa etc
I once joined in a virtual fajita testing night with other people with D.
This is what I ate:
2 Discovery tortillas, 40gcarb, red peppers 10 g carb, onions 6g carb , salad and salsa 5g carbs =61 g carb (I also had a few nibbles whilst cooking so added on 9g for those ) So for me it was a relatively high carb meal of 70g carb.
I calculated and bolused 5.7 up front.
Start 4mmol (well actually about 25 mins before, at the start of cooking)
1hour 9.1mmol
2hours 8.4mmol
4 hours 7 mmol bed
am 5.8mmol (I like to be a bit lower)
The overall results were very mixed. Some people, like you , were very high at 2 hours and had to correct to bring it down. Others seemed to have done as I did and had a sharp 1 hour spike (5.1mmol/l) followed by a slowish fall.
Surprisingly the one T2 had a very small rise.
Yes, there were a few problems but compared with some of the other 'difficult' foods,for most people it wasn't too bad. (Fish and Chips from a chip shop was much worse for many)
We quite often have fajitas when I visit my daughters. Since that experiment ,I either give a little bit more insulin than calculated ( I think a superbolus might be a good way of doing it, haven't tried) but more usually eat only 1.5 of the actual wraps for a meal Then I have no problems.
superbolus:

If i were you I would test again and see what happens at 1 hour. Then you can decide whether you can cope with it by changing the type of bolus or whether it's one of those foods that you have to eat less of/give up.
