I gave up cola's a while ago (only drink water) and I only ate WW products, and I hardly ever had sugars - though I would have 2 splenda cookies at night sometimes. However, on day 2 of Sonoma I still had a raging withdrawal headache. I do love fruit and eat a lot of it normally, but I wanted to start this diet off right so I gave it up for the 10 days. I think drinking a lot of water should help
