Is this a good method to use?

I think I am going to use this one.
I also have a question, if I ever get to the astral plane how do I go back to my body when I'm tired? I know I never will be tired since it will be so awesome. But just in case. How does it feel once you go back to your body you just snap into reality? Do you feel your self flying back into your body? Also how do these vibrations feel, may someone describe them.

This is just about the last thing you need to worry about! 

trust me, NOT doing this is far more difficult. If you even think about your body, there is a good chance you will end up back there, and you will find yourself rocketed back there for all manner of random reasons; you might feel sensations of a full bladder; you might hear a noise; you might be shocked by something in the projection environment and rush back to body; you might get a sudden thought about being a dis-embodied point, and indirectly mentally reference that to having a body, and snap back there; you might drift off in a sleepy fashion, and awake in body.

Some people seem to have a moment where they want to return, or are frightened or anxious, and have a shade of difficulty, but normally just planting the mild thought of being back in the body is enough to actualize that intent.

Dramatic. You might be unsure if you have experienced them or not, since you might be confusing them with nerve-tingling numbness sensations, but in occurrence, they are bold; they cycle at about 4-repititions a second, and pulse your entire body to near-earthquake amplitude. You might think they were mildly painful I guess, but I would say they are more suprising than anything. Some people never experience them, and go on anyhow, and most people experience them early, and they subside over the weeks and years.

Projecting from sleep paralysis I experienced the vibes as an unsettling (if you're not used to them) but gentle sensation throughout my being. Imagine yourself as the sound of a harp string that was just plucked. That is pretty close to what my vibes were like, though lately I sort of phase into projections instead.

That technique is essentially the Lucidology (saltcube) method.  It's a common and effective method, so indeed keep it up.  If you look on youtube for lucidology 101 or saltcube you can find a video presentation of the same technique. 

I feel the vibes as more of a light buzzing, but it only happens when I'm actually in the process of separating so I don't know that it is the same kind of vibrations other's experience.  Mine aren't loud, earth shaking events.  It's more like my whole body 'went to sleep' and is tingly, like when your foot goes to sleep.  I have always believed it to be what happens during the transition between physical and nonphysical when there are no concrete stimuli for the brain to interpret.  Instead, the brain encounters pure potential and we perceive that as buzzing or vibrating.  I may be wrong, it's just an idea.
