Leg stiffness and possible leg cramps when lying lying down?

Nocturnal leg cramps: This may be nocturnal leg cramps. The best treatment for this is quinine, but now the fda does not allow quinine to be used for this. It is very effective for this, does have side effects, but has never had formal testing. There are a lot of medicines we have learned to use which it never had formal fda testing. Unfortunately this is one we can't use anymore. Available treatment is now stretchingmaintain electrolyte balance.
