Of the respondents,258 individuals with insomnia werematched by age and sex with 258 normalsleepers.
The compiled data showed that peoplewith insomnia drink alcohol within30 minutes of bedtime more often,compared with the controls, and 29%consume alcohol as a means toachieve sleep. As for the participantswith insomnia who smoke on a regularbasis, 45.3% smoke 5 minutes beforegoing to bed. The study also showedthat the participants with insomniareport "sleeping in"on days they do notwork, with 42.7% following this model.
