If you have been vaxxed or live with someone who has make sure you get a Vitamin D supplement and take it daily from this point out. Low levels of vitamin D have been linked to fatigue, aches and muscle weakness, among other problems so if you are experiencing any of these symptoms it is possible that you are not producing vitamin D as you normally would. Do not take more than recommended as it will not help you more. Do this until advised otherwise.
God be with you all Patriots.
