Fuck pacing yourself, who the fuck does that anymore? You need to work on that tolerance bud. A bottle of Bushmills a day to start out and increase the dosage as per necessary. Switch to Gin after a week or two. You should be on at least a handle a day by the third week- and always keep a beer in hand. If you're gonna' do it, do it right.
By the time the wedding rolls around you'll be the motherfucking champion son. Hope they got an open bar and hot bridesmaids!
