I was trying the 30-day for awhile, but I'm back here now. Given how bad my recent relapses have been, I'm going to need the full 90-day reboot. So I might as well go for it. Day 0.
I've said it before, and I'll say it again. I swear, the hardest part is getting over that day 0-2 mountain. After that, it's reasonably easy. At least, it's not a constant urge... Oh, well. Throw 'er into four-wheel drive and hold on to your hats. We've got a mountain to climb.
