For me I'm super groggy when I actually get decent sleep but today nothing and no sugar today. Though was hungry so just had some cereal so that had some sugar on it. XD
Urgh, I've never liked that stuff, if you want caffine free, some root beers offer caffine free, and Spirte is a good option too, just avoid the diet stuff. Also stuff like Coke 0 is decent option too. (it actually lives up to it's name with almost no sugar in it at all. xD)
Yeah nothing much I can do about it but once in a while he will buy a normal bottle for me. XD I'm a sugar fiend if I drink coffee it's got to have 5 tablespoons of sugar in it or else it's just disgusting water.
Blue Jay, do you check your glucose count with your Dad's strips at all? If you don't you should check it once in awhile. Thirsty all the time is an indication of diabetes too. and diabetics have to watch their carbohydrate count.
