If you have trouble sleeping, you may be low on magnesium. Magnesium is one of three electrolytes that you have to replace on your keto journey. Electrolytes are non-negotiable when you follow a ketogenic way of eating. Replacing them daily is vitally important. I use this spray in the picture because it is an easy way to get my daily dose in and it is gentle on the digestive system. Magnesium can have a laxative effect in other forms. Just spray it on the bottoms of your feet 20 – 30 minutes before bed and you will sleep like a baby.
