Well, it took a lot longer than I expected, but Sunday night, by odd coincidence, was the 4 week mark with no subs. I won't write up a big play by play, since most of you can probably imagine more or less how much fun that 10 week period was.
Anyway I'm in a relatively good place. Still wake up with shitty cramps after 4 - 5 hours of sleep, but nothing a hot shower followed by a walk around the block can't deal with. Other than that, the fatigue and occasional bouts of sweating and joint aches, I'm doing quite well. Eating well, exercise twice a day (managed to start running again last week, which has helped enormously), got my daily meditation practice back on track and I can usually manage to get out and do shit for a few hours every day, although if I over exert myself I do crash pretty hard when I get back. Finding the right balance of exertion - rest seems to be the key. More to the point though, there are are tangible day to day improvements, even if they're sometimes quite small, so I figure as long as I can keep myself headed in the right direction then things should keep improving especially sincce it is, relatively speaking, early days.
Oddly, the psychological side is a bit more than I expected. I figured the hard part would be the physical symptoms and the grind of dealing with those and maybe some big resurgence in cravings (which so far hasn't eventuated), but it feels like the subs were actually numbing things out quite a bit more than I thought. I know everyone says exactly that, but it always just felt like one of those things people say, the assumption that if you're on an opioid then you're not getting the full range of emotional experience, even if you feel like you are. Maybe "everyone" is right in this case. It's hard to describe, except that the world seems a bit more vivid and intense than before. Quantitatively it isn't a massive effect, but the process of adapting to the slight but constant increase in input can be a bit jarring at times. But it is, I think, a good change, although I'd guess it'll take another month or two to adapt.
So that, hopefully, is that

There's still the valium, but I don't anticipate as large a problem there, and it looks a lot more manageable from this side of the suboxone. I figured I should leave this for posterity instead of disappearing into the ether like so many other BLers have done (not that I'm QUITTING BLUELIGHT FOREVER AND EVER, but this place is pretty dead and most of the old crew seem to have moved on, so...), and of course, say thanks to those who've offered good wishes and input (and apologise to those who I suddenly stopped replying to - I found the whole thing easier if I didn't ruminate on it too much, so I avoided long update conversations for the most part until I was over the hilltop).
