I have good days and bad days. On days I feel weak, I beat my brains trying to think about what in my diet or activities might have contributed. Sometimes it’s just overuse or fatigue with me. Sometimes I decide to take a potassium vitamin thinking maybe that will help. I do a little extra leg stretching while I’m sitting down. But I honestly haven’t cracked it - I find it runs its course and I have my good days back again.
