If you have sick days or vacation time you can take you might consider doing so. If not take the advice above and try to rest as much as you can while going through the withdrawl.

Withdrawl is tough but it does end. The one good thing about withdrawl is that it is a clear sign that you need to be gluten free whether testing shows positive or not.
