Okay, I have great experience with the morning glory seeds...
First off, make sure you get the right kind, not all kinds of MG are psychoactive. Try to stick with Heavenly Blues, Flying Saucers, Wedding Bells, Hawaiian Baby Woodrose, Oliliqui, and theres a few others that I can't exactly remember the names of. (I actually have 15 packets of Heavenly Blues right here)
Second, make sure you take the right amount. First time i did it i had 6 packets, 2 Heavenly Blues, 2 Flying Saucers, and 2 Wedding Bells. (Go figure, the ones i listed) Anyway, tripped sac for about 10 hours and then ended in violent projectile purging(vomiting). I would recommend no more than 5 packets. And keep in mind that of all of those strains, Heavenly Blues are twice as potent as the others, containing .02 percent LSA as opposed to .01. Hawaiian Baby's have .12 btw, so dont take more than 13 seeds. And you know you are about to trip face when you taste a metal-ish taste on your tongue, which at that point means that your body has successfully turned LSA into LSD...
Third, use the right method. Crush your seeds up into fine white and black powder(or at least small chunks), and put them in a bottle with distilled water, in a cool or cold dark place overnight, as heat and light break down LSA. This will turn your LSA into its actual psychoactive form, iso-ergotrine, aka iso-LSA. Your body will do this for you if you chew the seeds and swallow them, but you will lose much of the content through your digestive system, etc. Technically, after 1 hour, the LSA will start to turn into this form, but after 24 hours, it will have completely dissolved into the water. In order for you not to puke your brains out, just drink the water and not all the seed mush at the bottom of the bottle. DO shake it during this cooling period however, and its not bad if you end up drinking some of that mush. In my above stated trip, I drank all the water and mush, and seed casings. I thought i was staring into the universe swirling around in my toilet, although it was only seed casings and pink/purple... you get the point.
I think that about covers it. Smoke some weed when you ingest it because it will rid you of any nausea, and hold your hand on your way to trip land. I get a heavy body trip from LSA, so after you walk around and all, make sure you have a comfortable place to lay down. Great luck and let karma carry you well on your spiritual journey!
