Whilst I feel groggy every morning, I notice that I operate better when I don’t oversleep, if I stay up late and get up somewhat early, let’s say maybe 6 hours sleep, why is this? They say people need 7 / 8 hours of adequate sleep for good health.

You could be routinely breaking your REM cycles, and this shorter sleep happens to wake you up when you’re not in one.
If you can remember your dreams–particularly if you are aware you were in one at the moment of waking– then it’s *very* likely you are breaking REM, which causes your grogginess and low energy.
A full cycle is important and healthy, but getting two and a half cycles is still better sleep than getting just one, even though you’ll wake feeling better rested in the second case.
