Thread: WBTB Hours of sleep?

So the first night I tried a WBTB I slept for six hours and had an LD, the next night I tried it I slept for six hours and had multiple non lucid dreams.

Durring the week I have school I dont get much over 7.5 hours of sleep anyways, so I would hate to be up an hour before I actually have to get up. So how many hours backwards should I try so that, that sleep schedule works for me.

Thanks DV for all the help-Torin
