The guilt used to be really bad, and I've found that in the last year or two I don't really care after I end a binge. I've been down that road so many times that it's just old, and really it doesn't accomplish anything to hang on to the shame and regret.
It's the same for the day count. I used to go on long walks and just think about how I wish I had more days and how things were going to be so awesome when I had three months, a year, two years... Things never really turned out that way, nothing magical ever happened. You spend so much time hoping for the future that you completely miss what is right in front of you.
As for the actual relapses, they're pretty much the same. I'll go and pick up a bag and use for about a week, pretty much every single day. Eventually I burn out and flush the rest, that part has been pretty much the same for the last several years.
