2 days. The good news is I can already feel my brain pulling up the old "good habits" script and moving almost on autopilot again, just by starting the script from the beginning in the morning and post-work. It's still in there, I have just been operating on the older, worse script recently.
It's interesting this time around because it doesn't really feel like I need a new plan. I just need to actually operate the old one that worked for me again.
