The symptoms you are describing indicate that you are having nocturnal leg cramps. These can occur in patients of diabetes. Your PCP gave you the right medicine i.e. quinine. But if that is not helping then maybe you need to be put on muscle relaxants (such as methocarbamol or cyclobenzaprine), or other medicines like Verapamil,Gabapentin. But for this you need to get a prescription from your PCP. But in the meantime at home you can try a few measures-
* Stretching and regular exercise
* Drinking more fluids before and after exercise
* Applying heat to the muscles that have been cramping before bed
* Wearing better footwear, such as shoes or inserts with arch support
Also taking vitamin E and Calcium supplements also help in reducing nocturnal leg cramps.
