Not sure if this helps but i have been running on high BS for the past two years. Running between 16 and 28 with 20 being the norm for me. I can say that with my sugars this high it has changed the way I do things. I get down right nasty. It took me some time to figure this out but once I did I did have some success in knowing when I feel this way I go off somewhere by myself evening if it is the bathroom. My wife says I take the longest time in the bathroom then anyone she knows. MY point being if it helps you
If others around you understand what is going on and you can take control of your thoughts fo 30 seconds then take a breather away from everything. This helps me clear my mind and sometimes (not always) brings me to grips with myself and my surroundings.
Hope this helps you some.
