Primary outcome [1] 308292 0
Validated questionnaire for Hangover Symptom Severity.
As described by Hogewoning et al overall hangover severity was measured using a single one-item rating and severity of 23 hangover symptoms that was rated on an 11-point Likert scale ranging from 0 to 10. The 23 items were derived from the Alcohol Hangover Severity Scale, the Hangover Symptoms Scale, and the Acute Hangover Scale.

Brief summary
The aim of the study is to assess the efficacy of a natural treatment for the symptoms of the adverse after effects f alcohol. The product Rapid Recovery has been developed based on the scientifically supported rationales using several methods of reducing acetaldehyde ( a major metabolite of alcohol) toxicity which is believed to be a major mediator in the adverse after effects of alcohol consumption. Adverse effects of alcohol consumption will be measured the following day using visual analog scales of validated symptoms. In addition blood alcohol concentrations will be measured prior to commencing the study and at the end of the evening drinking and immediately prior to undertaking visual analog scales. Blood sampling will be performed on the first night of the trial and then on the morning after alcohol has been consumed. There have been reports that that there may be an inflammatory response due to acetaldehyde toxicity.
