Try Max Tabs [0] and force yourself out of your habit/workflow by needing to be selective with your tabs (or maybe you'll just learn to run more windows instead).
I'm pretty sure there are mass bookmark extensions. Get one of those and dump all open tabs into a triage folder; once a week go through the folder and move the ones you want to keep into a proper folder and delete the rest.
Hell, that ought to be an extension too. Autopurge a bookmark folder at set intervals.
