Hello again, thanks for writing back with more information. I was trying to see if you were on any medications that can cause cramping such as certain diuretics and/or BP medications that can deplete or alter your potassium and salt balance. Since you didn't mention any medications, besides the quinine, I am assuming you are not on those types. If you were, you may need to monitor your electrolyte balance more closely and make sure you are getting enough potassium.
It sounds like you are saying that your blood sugar is in a good range, but when you eat things with sugar in them, you have noticed that you having the cramping, but when you stop eating the sugar the cramps go away. Diabetics often develop symptoms of neuropathy, but I had not heard that sugar could cause cramping directly, but if you find that this seems to be happening to you, I would certainly try to stick to decreasing the sugars, since it works for you, and as it will be better for you to decrease simple sugars in your diet anyway.
As I mentioned above sometimes diabetics are more prone to getting neuropathy which is nerve damage in the extremities related to having decreased peripheral circulation and nervous system destruction. Neuropathy can also be related to several other factors such as high blood sugar, poor circulation, auto-immune disorder, smoking, alcohol, etc. So this could another possibility for your cramping. Neuropathy is usually described as feeling like numbness, tingling, or pain in the toes, feet, legs, hands, arms, and fingers. It can lead to wasting of the muscles of the feet or hands.
Here is a link about neuropathy if you want to find out more about it:
I suppose you have also heard of RLS (restless leg syndrome) which is mentioned a lot on TV commercials these days. This is usually described as an uncontrollable urge to move when at rest. Sensations are described as burning, creeping, tugging, or like insects crawling in the legs. I am only mentioning this, incase your discomfort seems more similar to this description rather than cramping. Additional information about RLS can be found here:
There are medications and treatments for both neuropathy and RLS.
I hope I have not given you more information than you need. I felt it was important to let you hear about these things, since you have risk factors for them and another treatment might help you if you did have these disorders.
If you are okay, and the cramps go away with stopping sugar, that may be all you need to do (as well as continuing to take good care of your diabetes)
