Is there a cure for my sleep problems?

So I'm not sure if it's deadly but I just woke up but I fell asleep two days ago, I'm worried for I cant remember waking up once at all and lately I've woke my self up and I was well um eating hahaha it was quite funny the first time but now I've done it 8 times and I'm worried I might end up chocking my self. Or falling down the stairs seeing as I'm one the top floor. I've already tried locking my doors and putting up a gate for kids at the top of the stairs but I end io unlocking and taking down both. I'm so tired but I don't want to fall asleep and be walking about or sleep till the end of the week!
