for the last 3 yrs, whjen i woke up and later in the day when sitting at my pc, I started to have treefold bilateral cramps in toes and both posterior calf and thighs (hamstring). I tried taking supplement soft caplets addressing lack of calcium, magnesium, potassium selenium and other to no avail. Then, I talked to my lumbar neurosurgeon and I asked him if the L2-L3 recent fusion were the root of these cramps old cramps. He replied no, it is electrolytes imbalance. I retorted, I do take the mineral straight in cap form. He replied electrolytes again. Ok, I went home thinking about his answer. I do trust my neurosurgeon and I said to myself how do I get the electrolytes into my system in an effective way ('cause the individual caplets were not delivering what I needed relief). Well, I did some research; the answer was alkaloid water form with enriched electrolytes. The first day I got the stuff home, between lunch and supper, I drank 16 ounces of the electrolyte enriched alkaline water. The next wakeup morning, what had been a ritual at first wake up leg retractions, bilateral posterior leg or thigh severe cramps well it were gone; faith in doctor advice. This is my 4th day of taking the enriched electrolyte. And from now on I will not miss my daily dosage of enriched electrolyte alkaline water. Please notice that the first gulp of the stuff felt like a light burning sensation on my tongue! I guess a differential of voltage born between my taste buds and the passing lytes (they are ionized I gures a battery effect). However, since that first gulp sensation now there is a balance of the lytes even in my tongue!!! This is what worked for me, it may nor work for you LOL. .
