the method i've used several times with morning glory seeds:

-wash seeds thoroughly w/soap and water, making sure to rinse ALL the soap off
-paper towel them off, then let them dry for at least an hour
-grind them up in a coffee grinder til they're about the consistency of coffee grounds
-put the ground up seeds in a water bottle half-filled with water (use bottled water, i've heard the chlorine in tap water can fuck with the LSA you're looking to extract from the seeds)
-let seed-grounds and water sit for 2-3 hours
-strain the seed mush out of the now-mucky water
-drink yucky water.

it'll take 30-60 minutes to start to kick in. taking an extraction instead of consuming the actual seed matter cuts WAY down on nausea and other stomach issues, almost eliminating them totally.
