its always 66 pounds per week when on full abstinence, when you enter rtm the number of packs begins to drop , first to 3 a day (49.50 per week) then after a whil 2 a day (33.00) then finally 1 pack a day (16.50) sorry i cant be more specific as to when you reduce the packs on rtm but it more than 2 years since i did it x
hope this helps xx
