Congratulations amazeme, I'm also on day 7!
I did feel crazy tired the first few days and probably still do....but it is a kind of tired I can manage (I can work and manage to get off the sofa to do things...unlike the debilitating exhaustion of hangovers that didn't allow me to do anything! At least now I don't have fatigue combined with splitting headache combined with dizziness combined with stomach pain from drinking).
Congratulations again!
