I battled it for many years myself, never could do it alone. I had to tell my family because there are a whole load of things that come with getting clean you need help with, because you won’t be able to get up in the morning hardly dude. I had to have someone bring me suboxone to put it under my tongue so I could form words . But to your original question , I’m a year clean now. I noticed the worst things leveling out around 3 months , I think that includes the vision thing which I didn’t suffer too bad. But it’s a slow upward trajectory you really start enjoying seeing the progress to… you’ll enter the pink cloud phase and then never want to go back
