Oh, Mary...how can I say this? That "small glass of pop" you're drinking now might as well be sugar water...well, actually, it is. By drinking it, you are making your thirst worse.
The reason you are so thirsty - and only doing blood glucose testing will confirm this - is because your blood sugars are running high. That's what I suspect, given that you are Diabetic and incredibly thirsty. Are you Type2? What type of Diabetes meds are you on? Have you been recommended to a Dietician yet? You are new to this but, one of the most important things you can understand is how food, and that includes drink, affects your blood sugars. You'll be amazed at just how much sugar is in products, and you'll understand just how incredibly bad that little glass of pop is. Most Diabetics use pop exclusively as a quick-fix to stop a hypo/low.
To directly answer your question
.......water - best thing ever for thirst. Period. Spice it up a bit by squeezing fresh lemon or lime - not so much that you need sugar, though. There are numerous "diet" sodas, ice teas, powdered aides, etc. that vary in the sugar substitute used and affect people differently, so you'll make your own educated choice there.
That being said, however, you MUST stay away from or severly limit: 1) fruit juices - eat the fruit instead and also understand how high in fructose (form of sugar) some can be, 2) regular soda/pop/lemonade/etc. - they're just bad, pure sugar. Sports drinks - some are high in sugar but most are really high in sodium - that's salt - not good unless you're actually exercising to have such a requirement (retain water).
I'm sure there are folks who can suggest a lot more sugar-free drink options but I hope I've helped you understand a little bit. Best of luck. We're here for ya
