a "dumb" dumping question

sounds like you may have a BS meter on hand.  If you can - test them on yourseft. 

first thing in the morning - don't drink or eat anything bu****er. Measure your BS. Then eat 1/2 bar. (since 1 bar made you sick) .  Measure your BS every 10 min after you eat the bar. Record the numbers.  

most people get 5 point BS increase (typical) for every gr of sugar (or food that body sees as sugar).  Measure the highest BS number.  

Then take than number - and subtract the number before the ate it.  That way - you will know how to measure how much "sugar" your body got. 

i.e. my BS was 100... then my highest BS for this bar was 200... and then it started dropping.  so the 200-100=100 points BS increase for me.  Eating the whole bar - my body absorbed 20gr of sugar.   I saw over 50 points increase for 1/2 bar... = 10 gr of sugar for my body. 

BTW: When my BS drops due to RH - I know exactly how many glucose tables I need to get it to normal and not get that too high... 

That is how I know how many sugars take to raise my BS by 100 points 

(I took 2 glucose tables - each 4 grs = 2x 4=8 gr x 5= 40 points ) When my BS drops to low 50's I need at least 2 glucose tablets. But when it it in low 30's I need 3 of them to get my BS back to 90's. then I can get some fat and proteins.
