There's no rule that says you have to count days - if it make sense to you not to restart your count then thats up to you.
I was a pretty good rationaliser tho -if I had say 6 months with 2 days of slips, it wouldn't be too much for me to rationalise that 6 months and 3 days or 4 was that much worse...
whatever you do, count or don;t count, the aim has to be no drinking, ever, any time.
If your recovery plan isn't geared to that, maybe you need a better plan?
