My husband calls them his demons, he says that they are always there but he can usually control them, he says it’s like locking them away and listening to the other side of his brain, but it’s like he can always hear them banging waiting to be released.
He was in a v bad way four years ago and the demons were telling him o jump off a building, that was his lowest point I believe, and that was when he realised he needed to get help.
I would say its prob more likely they might get worse through withdrawal from my experience before they get better, because the drugs are not numbing the pain or the thoughts as much and when detoxing you always feel worse before better.
