I had to stop being so invested after the auburn loss in either 05 or 06. The one with blatant pass interference at the end that wasn't called. I still get upset when we lose but it doesn't ruin my whole week.
That was in '06. The AU game in '94 (the Jamie Howard Interception Game) had me run down for around a week. But that was in my younger days. I really don't have the time or energy to focus too much on losses like that anymore.
