Just don't do it when you are driving, here is a post from the local Constabulary about a very successful operation they recently carried out. The results appeared on local TV and press so was very effective.
I certainly wouldn't rely on any machine to check my alcohol level, it's only electronics that is made for a price. Great for a bit of home entertainment but not worth risking someone else's life or your license with.

Major operation targets poor driving, traffic offences and criminality in Plymouth area
From the evening of Monday 12th December and into the morning and afternoon of 13th December 2016, roads policing officers from Devon and Cornwall Police and Dorset police took part in a day of high profile activity concentrated on Plymouth’s city centre roads and the A38 corridor from Plymouth into Cornwall.
106 offences were detected during the short, intensive operation.
The operation employed liveried and un-liveried roads policing vehicles equipped with automatic number plate recognition equipment (ANPR) and an unmarked HGV lorry cab was also used, giving officers a birds-eye viewpoint of drivers committing offences such as using mobile phones while on the move.
40 drivers were identified committing an offence by using their mobile phones behind the wheel.
13 vehicles were seized because the drivers were uninsured.
There were two arrests for drug driving and 12 vehicles were banned from the road for being unroadworthy.
A 17 year old tractor driver on the A38 had his license endorsed and was given a £100 fine for using his mobile phone to check Snapchat while driving. He was caught by officers using an unmarked car.
On the morning of Tuesday 13th, a dozen drivers were given verbal advice for driving with alcohol in their system, classic cases of “the morning after”.
Chief Inspector Adrian Leisk, Head of Roads Policing, Alliance Operations Department explained: “Drivers must understand that if their judgement is impaired because of alcohol or drugs, then being “under the limit” will not prevent them from being arrested and possibly prosecuted.”
“It takes one hour to process one unit of alcohol. If you’ve been out and had a lot of alcohol to drink late into the night and are thinking of driving the next day, you do the maths. It’s not worth the risk to yourself, other road users and pedestrians.”
