I've had difficulty sleeping at times and woken with the knee and back painfully locked up solid in the morning. All symptoms of the above. Ruins my morning. To pun a phrase it really cramps my style. I've been doing plenty of water/tea hydration but that wasn't enough.
Last night I took mag/zinc/calcium and drank coconut water. Had nice lucid dreams, excavated easily, and woke up feeling refreshed and 'normal' again. What a difference.
