When you're done, you'll be asked to stay and relax, and have some cookies and refreshments to replenish fluids. While most people are fine immediately afterward, a few feel slightly weak; but the feeling passes quickly. Within a few minutes you can return to school, work and most other activities. You can help speed your body's recovery by:

• Drinking extra fluids for the next 24 hours.
• Not smoking for one hour.
• Refraining from heavy muscular or strenuous activity, such as lifting or pushing heavy objects, for at least four hours.
