Another point for WBTB! Ive found out that 90 minutes works best for me when I've slept for only 4-5 hours, and I stay up for 60 minutes if Ive slept 5-6 hours. And longer than that, just a half hour, but I try to keep it between 4-5 hours...works best.

This is the best LD's community i have seen around, keep going with the good work See ya![/b]
It's quite an amazing community. Its amazing the success that comes out of here every day.
