The LSM tabs were also incredibly bitter (one person even gagged and puked up a bit just trying to swallow one, they tasted like total shit). Effect wise they felt a bit more speedy than LSD, lacking in the deeper psychedelic effects to some extent, but with a much more club drug, rushy, euphoric feeling to them. It felt like a close cousin of LSD, notably different but obviously related. My favorite part about it was that I could take it multiple days in a row and still get good effects, something that is next to impossible with LSD.
