When my husband was cramping, we tried alot of things, Potassium, pickle juice, vinegar . . any old wives tale we tried it. Then on a 3 -4 day vacation @ the hospital, they gave him Magnesium. No more cramps . . as soon as he was out of the hospital they started again . . we determined that the meds he was taking was stripping the Magnesium, along with dehydrating him and that is where the cramps were coming from.
Post transplant he is still taking a Magnesium supplement 1600mg a day.
My opinion is that the dehydration, from the liver not processing is the reason for the cramps, because he had them long bfore he was on any medication. Even though you may be drinking water/fluids to hydrate, it's not going to the muscle, causing a cramp. Soon, the water he was drinking went straight to the belly/Ascities .
When first diagnosed w/ESLD, my husband drank lemon water, and he actually felt a little better and his MELD score dropped . . it may have been in his head or mine, but it can't hurt!!
