intake is reduced, the body then becomes oversensitive to a chemical in the brain (adenosine) relevant to the sleep process, causing blood pressure to drop dramatically, producing an excess of
blood in the head area (not necessarily on the brain), and leading to a headache often lasting several days. Other withdrawal symptoms reported are fatigue and muscle pain, irritability, inability to work, nervousness, restlessness, and feeling sleepy, and in extreme cases, nausea and vomiting. Gradual reduction of caffeine intake abates these symptoms.

Most of the studies under review reported positive associations between caffeine during pregnancy and the risk of spontaneous abortion. They are, however, inconsistent in the magnitude of effect at different levels of intake, and major differences in study design and statistical analysis prelude direct comparison of their results. Because of this, and because of the difficulty in quantifying the net effect of likely biases in each of the individual studies, it would be imprudent to pool the results of these studies to arrive at an average effect of caffeine, as has previously been attempted.
