For me, the body load isn't so bad, but it's just part of the drug.
In my experience a water extraction is a much different experience. More of a wide, euphoric, trippy drunk, but still a worthwhile trip. Chewing the seeds however makes it more psychedelic imo. More nausea, but ginger does help. I've never done ether extractions or know anyone who has, but this chart makes me believe it may be less effective or atleast not cost/risk worthwhile. An alcohol extraction, and or with peppermint oil allegedly converts the LSA to LSH, being more visual.
