What to Expect Calendar (Symptoms) in Resources Posted 3 hours ago 12 hours ago, Linda2404 said: I am in day 10 - got through yesterday fine - I was the host for a family dinner so all I made was Whole30 compliant but today Day 11 I feel like I have then the flu! Is this what it means by days 10 & 11 being the worse? I’m so achy and tired! Help! and thank you for your support in advance! Might be Whole30, might be that you have a mild cold or flu. Either way, drink plenty of fluid, try to eat something if you feel up to it, and get some rest. Hope you feel better soon!
