Charlie Horses? Anyone else after having lost so much weight

I used to get them at night if I had not had enough fluids during the day.  Drink more water and have your labs checked.

   You can wait and go to get labs if you want.....but  I stopped mine with SEA SALT!  
       it is naturally high in both potassium and magnesium. My PCP recomended it....after I began having  cramps on a regular schedule.  I make up some about a cup of koolaid and add  a half teaspoon  sea salt  to make an emergency gatorade like formula. Doesn't taste too bad that way.....but if I start cramping I put some in my hand and  lick it up then follow it with water. I do this every 30 min until all my cramps are gone...continue to drink much water.... 

thank you all

I used to get them all the time.  Someone suggested tonic water with quinnine. I started drinking some before I go to bed and they have disappeared.

Thank you  :-)   My mom drinks that stuff, blech!!  I can't handle the carbonation.

I keep a bottle in my room and let it go flat.
