I think is a matter of lose the fear and let it go....in some way it remember me the day I learned to ride a bike...once you lose the fear anything is possible,....
...in one moment I was shaking and the next riding my new bicycle!
Dose is also important.I think is a matter of experimentation to find yours. And I think that meditation is another key, try to reach the launch with your mind as calm as possible,it makes the difference.
Been two days since my first visit to Divinity( or hyperspace,or Zero Point Field or whatever you want to call it) and even my happiness persists, think more clearly and feel more connected to everything,,,,
Good luck friend...Keep in touch
