The effects of LSA occur over a long period of time, much like dextromethorphan plateaus. It takes 2-5 hours for the seeds to be digested and the LSA to begin to work. Depending on the dosage the first part of the trip is the most nausiating I believe. I ussually bash up my seeds and put them in jello to set, then swallow lsa-cubes. The onset of the trip sometimes needs to be 'triggered' or set off by something, an abstract thought, a funny joke, music, you know.. something trippy.
As far as hallucinations, you wont' get many full-body hallucinations, maybe a few. By full-body I mean they have some resembelence of reality, like chairs floating or wallpaper moving. The most intense of the hallucinations caused by LSA, especially from chewing the seeds, I've noticed, is basic grometric patterns in the dark or as a CEV. They always seem to move very fast for a moment, and then stop completly and start again for me. I find music very hypnotizing and catatonic with this 'drug' personally.
Oh my GOD, what kinda coffee have YOU been drinking?!
