I worry about this sometimes. But here's what I do. I can tell the difference in the taste. The sugar ones taste syrupy. Ick. I can tell the difference for sure if I take a quick suck on the straw of a good amount. If I can taste the artificial sweetener in it I know I'm good to go. As you drink diet drinks exclusively and never touch the sugary stuff, after a while you'll be able to tell no problem.
LOL: next thing we know everyone's going to be carrying around Ketostix as avidly as we do test strips, and we're going to get weird looks from doctors....
I used to do this when I was first diagnosed and it was great, it really helped and made me realize how many people at fast food places just don't care or pay attention to your specific orders (my mom always had to say "we need diet, my daughter's a diabetic!")
Now, I find that I can tell on my own if a drink is regular. I find it tastes awful! I can't stand sugary drinks, and can't stomach them even when I'm low.
People already have gone through the whole I-carry-my-own-Ketostix pheomenon...remember the whole Atkins craze? I tried to buy some Ketostiz in the local drugstore, and they were sold out, again and again...because normal people w/o type 1 were on Atkins and just HAD to have the strips to...get this...make sure they were where they were "supposed" to be! HA! That was so strange.
lol, im lucky in this case. before i was diagnosed I would upchuck if i drank I a diet pop ( diet coke or diet pepsi) so I could easily tell the dif. but when i was diagnosed I knew it would be best if I learned to like diet pop, which i did. and now, I can tell the difference by sense of smell, and if i cant tell I take a small sip, and if I gag its regular lol, funny how things chnge after a few years. btw I cant stand coke zero, when it came out I luved it, then i just was all for the diet coke not really caring, then i tried coke zero again. it tastes really... wierd.. compared to regular..
but anyways, wow thats an awesome idea!! lol, except i'd be scared that the urine sticks would poison my drink....
