Safest and cheapest way is to not drink & drive in the first place, catch a cab - bus or some other means of public transport.
Lose your license, pay a big fine, possibly lose your job into the bargain and it becomes extremely expensive.
Sorry for the lecture but it is the only safe way.

Thanks Yarney
As for the original poster, there are many different types on the market, so it's hard to say all are accurate. Best to do as Subyroo says and don't drink and drive.

We have one called an enforcer 3 which is accurate to australian standards. Unsure of its accuracy compared to a police one.
Its brilliant to have as an indication. Im a P plater so its mainly useful to check im completely clean in the morning after a big night.

Specs and operating wise they are different they just share a casing.

The alcometers that you buy from the shops can be accurate to start with but the trouble with them is that as far as I am aware they are never recalibrated once they have been bought. The ones that the police use are calibrated every 12 months to ensure their accuracy. Also as any police officer will tell you they are only an indication (Fairly good one though). Once a positive indication has been obtained the police will then take you for further breath analysis on a fully scientifically calibrated instrument.

The breathalyser i bought should be calibrated every 6 months or 200 use which ever comes first and the company where I bought it would be the one to calibrate it. Yes the basis would be that of the police officer, but at least if you just had a drink you can test yourself before driving. I have a friend he would test himself before going to office if he was drunk the night before, because for some people the alcohol stays in the body that long.

I read this : A lot I'm sure doesn't know this
Why must I wait 15 to 20 minutes after consuming food or alcohol to ensure testing results are accurate?
A breathalyzer is able to calculate this percentage using only a breath sample because of the precise relationship between alcohol in the blood and alcohol metabolized into the lungs from the bloodstream. As such, it is important to make sure the mouth is clear of contaminant (including alcohol) so that the breath sample contains pure lung air, or as close as possible.

You need to wait a while after your last alcoholic drink so the breathalyser gets an accurate reading. So its reading the alcohol in your blood, not your mouth.
I wouldnt think it matters when you've eaten as long as its not alcoholic, eg, tirumisu or trifle, etc.
Note also that mouthwash & cough syrup are highly alcoholic & affect your BAC & breathalyser readings.
