If anyone can advise me as to how to avoid, or treat, the agony of muscle cramping, please write. I take 200 mg. of Quinine, which I order from Canada, every night. However, for the past two nights, it wasn't working. at 2:00am, when I was still trying to walk off the cramping, I had to make a choice: Take another Quinine or risk a heart attack and even lower platelets. I took the extra Quinine. When I speak to my doctors about this, they have no answers. All I ever hear is "You have Lupus." That answer only infuriates me. Has anyone experienced this and what can I do about it??????? What else is there besides Quinine???? A lot of my labs are abnormal, courtesy of the above diseases. My potassium level is normal, so it's not that.
