What I did was wake up around 6 or 7 and drink a mug of warm water. Later magnesium citrate (you won't get me to take epsom salt!!!). I wasn't even hungry. I ate breakfast when I became hungry -- a little cereal was all I felt like.
If you go back a page or two on this site (page 48?), you'll find my "first flush diary" parts one and two.
It'll tell you everything that happened to me, hour by hour!
