Welcome Placebo,
I am off the opiates for a month + now and am exactly where you are! I feel spacey and am certain I am going through extended withdrawal/paws (aint nobody got time for that!), so I am slowly increasing my exercise/treadmill, and healthy food intake, and setting little goals for myself each day.
Right now, I am trying to be as kind as possible to myself, and stay strong to recovering on MY time. Nobody else will affect my timeline. I failed in earlier attempts because I put too much importance on other peoples expectations, got stressed out, and couldn't live up to them. So, now this time it is for me, and I feel so much stronger and game for the daily battle doing it this way.
