But the one I liked best was actually proved to me.
Alcohol makes you med faster. (This is before UI's that showed a value to your mana pool)
If you sit and med (and does anyone remember staring at their spell book at lower levels while medding?) you could watch your mana bar go up.
If you drink a lot, the mana bar would go up quicker.
Of course, noone ever explained to me that my mana pool had been cut by more than half, so of COURSE it was going up quicker as a percent.
Sigh.....
