Aye, I know what you mean - I also miss the times when I could spend the whole night working (or gaming) and not feel even a hint of exhaustion later. If you're feeling tired now, wait till you reach thirty :P

Sadly, I can't help you with your issue since I use Winquake and have no experience with GLQuake.

Recently I found a very good source port for Wolf 3D / Spear of Destiny (it's based on zDoom!) called "ECWolf" and I am eager to try it out these days. It looks very true to the vanilla game, but it adds a few convenient features, such as an automap (yay, no more getting lost in mazes) and widescreen resolutions (it looks perfect). It has full support for the SoD mission packs too, which is great.
