He received a 17-week prison term suspended for two years.
He was stopped in Marine Parade East, Lee-on-the-Solent, on April 20. He had 121 microgrammes of alcohol in 100 millilitres of breath, around three-and-a-half times the 35mcg legal limit.
He was banned for five years and must pay a £115 victim surcharge and £85 costs.
