Leg cramps - milk always stopped this for me. I only got them when for some reason I wasn't drinking as much milk as normal (for me, which is about a quart to a quart and a half per day). Now that I can't have that much milk (because 12g carbs per cup, and I don't drink ONE CUP of milk at a time) I ward the leg cramps off with calcium supplements
RE foods that allegedly CAUSE diabetes: This is a total myth. They are now even starting to recognize that being overweight is not a CAUSE of diabetes type 2, it is a SYMPTOM. Sugar intake doesn't "cause" diabetes. Eating fruit doesn't "cause" diabetes. Either can make underlying diabetes obvious by causing symptoms to flare, though.
RE Fruit: Some people tolerate fruit very poorly while others tolerate actual sugar very poorly, and some can't tolerate either. I don't know what it is about our metabolisms that makes the difference. I can eat a cupcake once in awhile with no problem but watermelon (and many other fruits, including bananas) will give me the sulfur burps in no time flat. I don't eat watermelon at all any more, and if I limit myself to just one banana 3 to 5 days a week, I'm ok. I can have a couple of small apples. That's it. But no amount of sugar (That I can tolerate at any rate) EVER gives me the sulfur burps.
I use liquid sucralose in my tea nowadays, and I've actually found that adding a few drops to a bit of peanut butter makes a high protein low carb snack that I can stand to eat (don't care for peanut butter as a rule). I think it cuts the salty flavor, it doesn't actually taste sweet this way. About a T of this seems to cure the munchies, which I fortunately don't get often. Even that small amount is filling for me, where sometimes if I've been eating a lot of meat (which you almost have to do when you can't have carbs) I find that not to be satisfying. Next time I buy peanut butter I'll try a low salt variety (as well as sugar free) and see if that helps with the palatability.
These days I am relying heavily on stir fries sans the usual rice accompaniment, or with shiratake noodles that I find in the fridge section in Asian groceries. Lots of tofu, lots of paneer dishes. Wish I could find more diabetic friendly packaged foods given that cooking hurts my back and I tend to avoid it now that there is only me to cook for.
If you have only tried shiratake noodles as a pasta substitute and found them nasty, I agree, as a pasta substitute for Italian and similar dishes they are awful. They're great in stir fry though. Lots of fiber and no carbs unless you get the type made with tofu, then there are like 2 or 3 carbs and 5 calories in a 7 oz package. Otherwise the are 0 carbs, 0 cal.
