I really enjoyed doing morning glory seeds. I eventually was doing about 1000 seeds of the heavenly blue variety, which were untreated. I did them many times, and only once had an unpleasant trip. I would just go for a walk down this nice trail, and a couple times climbed up a couple trees and just sat there for like an hour listening to music.
You know whats funny is Me, having done them before, and my friend, trying them for the first time did I think about 800 seeds on a long hike, and he actually vomited and I didn't. These were untreated seeds, and as gross as they are if your chewing a shitload of them, I've never felt the need to puke, and usually do not get much, if any, nausea. So I imagine it is different for everyone. And I have also found that they sometimes take a good 1.5 hours or more to really start taking effect. Try eating something like 45 mintues after you ingest them.
Also, I had good results buying the Largest size gelatin capsules off ebay (Size 000) and filling those up (and packing them tightly with like a pencil or something) with seeds that were ground in a coffee grinder. Saves you from the nasty taste, but it takes some time to fill all those capsules, as it takes quite a few, although they are pretty cheap if you find the cheapest price on ebay.
Also, beware of some seeds sold that do not seem to contain any, or very little LSA alkaloids that are sold as one of the verities that are supposed to contain LSA. I bought a pound of seeds from the ebay seller worldsatellitetv and they had almost Zero effect, even at 1000 seeds. My original order from a different seller sold me 1/2 a pound of seeds that were great.
... time for me to get my hands on some more LSA containing goodies!!
