He says, "Those were the days of experimenting with scotch and Coke, and brandy. It used to bounce off us - that and all the travel we did in the van. If I had to do it now, I probably wouldn't last a week."
But Wood lived the boozy lifestyle for 45 years until finally getting to grips with his bad habit in 2000.
He admits he struggled with sobriety at first - especially when he was on tour - but nowadays he's rarely tempted to pick up a drink.
Wood adds, "It gets easier. The first few months I thought, 'Oh God, how am I ever gonna get through this?' But now I see everything in a different light, and more clearly."
The rocker has released a new book inspired by his 1965 tour diary, titled How Can It Be?
