premature morning glory seeds

I have lots of morning glory plants growing all around my yard. The seeds not fully dried yet because my plants are still in season. I noticed that if i pick them a little early, i am able to peel the black shell off of them because they are still soft, leaving a green seed inside which is also soft. I have heard that the black shell is what causes the nausea? (aside from chemicals which are not on these seeds). I have also heard that premature seeds are more potent that dried ones.? So i was just wondering if any shamans out there grow morning glories and are familiar with ways to use premature seeds except chemical extraction. I am trying to avoid nausea do to a bad trip before, so i am hoping that peeling the black shell will do the trick, or some kind of Pure water extraction using a tea bag, any info will help. But i do not need any information on dried seeds because i already know. I have also heard chewing the green seeds, letting them sit under your tongue, then spitting out the solids works, but that has mixed reviews. i have also peeled the black shells of a handful of seeds and let the green seeds dry till they were hard but i am afraid that if i let the green seeds dry out they will loose their potency. PLEASE someone with a lot of experience with fresh morning glories HELP ME!!
