Yes if an addict really wants to stop only for himself/herself then yes indeed they can stop......but you have got to want to stop for you,,,,,,,not for your spouse or your family.....the decision must be made by you and for you so you can better your life,,,,i have spoke to tons of rehabilitation facilities across the US and thats the anwer i have always gotten. So yes i have stopped for 3wks.....its not easy but i take it 1 day at a time. trust me it can be done....good luck
