Mind kicks me when entering sleep.

I'm new here, so I'm really not sure how to ask my questions. Hope I'm doing this right. Ok I have been trying to astral project for years now. I have studied many ways of relaxation and methods of projection and so far nothing has worked. I have recently figured out away of relaxing myself to a point where my body begins to sleep and I begin to rise from body...but that's where it all ends. It's like my mind kicks me awake! "It's like hey where do you think your going...OFB...I don't think so!" Just can't seem to get past this no matter what I try. Can someone please help! Also often when I try to reach deeply relax states I tend to feel sick; is this normal? Appreciate any help or advice. Thanks

I used to have this and other similar problems with astral projection. I realized that all you have to do is ask for what you want.

Ask for the white light to make you mobile.
Ask where you would like to go.
Tell yourself (or whatever higher power you use) how its going to be! almost like you're demanding or expecting it.
The only tricky part is not allowing your consciousness to take over..because then you wake up.
