Hang on. That quote I used says it's much harder to wake up once you go past 90 minutes of sleep. Which is what I was trying to convey in my post. You dismiss that as untrue and now tell me it's a fact? I posted my opinion from what I know and my experience. I don't go around telling everyone that's not true and it's a fact. What works for one might not for another.

I said "I agree on the point it's far worse to get up again once you're not ready to wake up."

Jesus...

it takes time to get into deep sleep and then everyone needs about 90 mins of that to allow your body to repair itself. Thats really minimum requirements each day
