This does answer the question very well. And it is natural. And there are many documented cases where these applications have proven very successful. Bob...you are kind of nutty on trying to squash the more natural system remedies. A body is a natural system. Anesthesia drives one towards an unconsciousness. This can restimulate previous times when a person was unconscious (unaware), and usually pain is affiliated with it. Most people do not recognize it, but past moments of pain and unconsciousness restimulate and affect an individual without their knowledge of what is really happening, (similar to being hypnotized). This occurs in the course of daily living and actually results in most of the aberrations of an individual. Unconsciousness is in the direction of death or dying, so of course, it is traumatic for an individual. A good thing to do around a person coming off of anesthesia is to have a calm, quiet environment. No talking or music or chatter. Touch, or gently squeeze and release the body's extremities, like the feet or hands. Reach with a touch and let go. The intention here is that you are trying to help the person get back in communication with the body. The drugs have dramatically put the person out of communication with the body. This will assist a person and relieve some of the nausea. Vitamin B1 would be helpful once the person can drink, so the person won't have nightmares. So, again... a remedy to help relieve a person coming off of anesthesia is to have: a calm and quiet environment, and firmly, but gently, grasp a foot with your hands and slowly release your grip. Do the same on another foot. Hold and release a hand or a finger. Repeat this type of touching in a gentle, caring manner. Keep up this procedure of grasping and letting go of a body part until the person becomes a little more stable. This will help the person to "come up to present time". It puts the person back into better communication with the body. The drugs have knocked the person out of communication with the body and environment. It does work. I know from personal experience on both sides of the equation.

My answer refers to general anaesthesia as Iv'e had both local and general. If you are being given anaesthetic drugs by a proper Anaesthetist then they should automatically give you anti-emetic drugs if you are showing signs of sickness. These alleviate the nausea associated with anaesthesia, unless you're allergic to them...like me! Prochlorperazine is a great drug which reduces nausea. A natural way to relieve nausea is to sip a cup of ginger tea. Tastes nice too!

One of the most effective anti sickness drugs there is is called Ondansetron. It is commonly used by patients undergoing Chaemothearpy. After a general anaesthetic, it is quite likely that if you're not allergic to it, the doctors will give it to you intravenously (through a needle in your body). This means it gets into your system more quickly, and is more effective than if you swallowed Ondansetron melts or tablets.
