I have suffered with leg cramps myself for many years. Mine are caused by the large doses of Lasix I take for a neuro condition called pseudo tumor cerebri( also called intercranial hypertension) I take 120mg of lasix a day. My Dr's decided to test my calcium, potassium and magnesium levels after I started getting eye twitches along with the leg cramps. All my levels were in the basement. I now take otc calcium, 1200mg 3 times a day, 250 mg of Magnesium twice a day and a prescription strength potassium ( 20 mediquil) three times a day. This has helped tremendously. I had tried eating bananas and taking otc potassium, but it wasn't enough. Maybe this is something that you can try. It was great for me.
