It sure sounds like you are going through the expected die-off. Make sure you read through the forum stickies as this topic has been answered before: http://www.thecandidadiet.com/forum/yaf_postsm9759_DieOff-Symptoms-and-Cure.aspx#post9759
Also, remember, your body is NOT just going through die-off. Any time a person goes from a unhealthy diet to a strict, healthy one, your body releases MANY toxins. Expect this to get harder before it gets easier. Keep your focus on the end result, you, and your health.
All the best,
