Did he go through withdrawals before starting the subs? For me subs did not help at all with H withdrawals until about the 4th day and the worst of it was over already. I am not quite sure why that was because I hear of people saying how they avoided withdrawals with sub, but not me no matter how much I took.
So how is he able to pay for his habit? I would think if he is a daily user he would have to be using at least $50 a day which is over 18 grand a year. I know that is a drop in the bucket for some people, but if you have a child together I think that finances could turn into a major issue if they haven't already.
You are in a sh*tty situation no matter how you look at it. A 2 month old?? Wow congratulations!!! I can't imagine what you must be going through emotionally right now. Kids definitely change your perspective. I hope it changes his. Good Luck!!!
