Doris,
I actually think that the fact that the tablets don't taste so great is a bonus. The taste helps me avoid overeating. The way MY mind works is I want to treat the low appropriately and get off the low-high-low-high roller coaster as soon as possible - this is one ride that is just TOO SCARY!
On top of that, I really want to avoid using coke, cake, cookies, etc as some sort of wacky reward for going low. Again, to me that's the road to some sort of disaster and/or eating disorder - YUCK!
Another thing I’ve found recently is Cran-energy, cranberry juice w/ a bunch of gatoradey/ Red Bull sort of vitamins and caffeine, which it claims to be the gentler kind distilled (sic?) from Green Tea? It is very tasty and has 9G of carbs/ 8 oz instead of like 28 or 32 or various other amounts (I have tried most of the different cran/ blueberry/ pomegranate drinks, usually looking for potassium as I loathe bananas…). It seems to have a very pleasant vibe to it and takes me out of lows very nicely and has worked really well before exercising, not a huge hit of caffeine or carbs but enough to get the job done for lows. I wouldn’t give it to a kid but it might be a good alternative? I still think that 10G of carbs and 20 minutes can kill a lot of hypos w/o the post hypo spikes so that may be of use to experiment with?
