me and my girlfriend did it, they've never bothered me but she brought it up a few times during the trip. you also need to be sure you have untreated seeds, most of the ones you find in local stores and seed packets have a chemical sprayed on them that will make incredibly sick. if you do an online search you should start seeing bulk "untreated" seeds. Also, just like LSD, heat kills LSA and you want to make sure you have fresh seeds or the potency will go down. some people say the cold water extraction method stops the stomach problems, but i have no personal experience. Also, the LSA trip is more of a chilladelic kinda thing. Acid always makes me want to get up and be active, with the seeds it was more fun to just chill, burn down, and watch the visuals
