It really depends on how many you were eating before, but you have the right idea to reduce them gradually. I started on 150g in February and am now down to less than 100g. Remember that when you reduce carbs you also reduce calories (energy) so to replace this you need to increase either your protein or your fat or both. Most people here increase their fat intake as fats don't affect blood sugars at all, whereas protein can sometimes and too much protein isn't good for your kidneys. Keep a food diary and write down what all the nutrients are keeping note of amounts of carbs/fats/proteins/fibre. I increased my fat intake by ditching all the low fat/zero fat stuff and returning to proper butter, proper yogurts etc.
High release carbs are the first thing to reduce or avoid - potatoes, rice, white bread, cereals, pasta, pastry, batter, and watch the fruits as they contain a lot of sugar. Try berries, they are the best. As a general rule tropical and Mediterranean fruits are the ones to avoid or keep to a minimum.
