Hello - First of all, Thank You for your order! Secondly, the teeth grinding is your body being uneasy. If you have parasites, your body is constantly fighting them and their toxins. This is what causes many parasite infection symptoms. The body can't be at total rest because of the constant internal battle. This is also why many people who have parasites wake up repeatedly during the night - they never can quite get to sleep as good as they should.
Good luck to you and your husband and please keep us posted!
