I see why you're worried. The lack of sleep wont help you with your new job role for sure. Did you ring a sleep school yet? I am curious what they have to say about this.
As I said, I had a friend of mine with a 2yo who did this and he eventually grew out of it. Though she was completely run down at the end of it.
The use of the plastic mats was just to help her change the bed quicker, but it didn't really stopped him vomiting all together.
