Meditation when sleepy?

[lmfao]

Hey guys, I was just wondering whether you meditate when sleepy. Whenever I'm sleepy and trying to meditate, my mind gets lost in thought much more easily than it does than when I'm alert. Is it possible to completely overcome the sleepiness by being mindful of it?

If you meditate with enough mindfulness, does your body natural become alert? Are the most hardcore meditators immune from the effects of sleepiness when meditating? I remember Leo talked about monks who could meditate for 7 days straight without sleeping.

I let myself fall asleep during mediation  @lmfao

The reasoning is that when I wake back up after 10-20 minutes I continue meditating and just label that I fell asleep.

This has a huge impact on my well being later on the day, so I don't mind it.
