I have tripped on ambien around 5-6 times, and I've found the best way to get a fun mindfuck and some pretty weird ass morphing/moving/dripping visuals is to eat 10mg, and around 15-20 minutes later snort another 5-10mg (depending on how fucked up you feel like getting and how long you wanna sleep for afterwards). The snorting seems to kickstart the trip into gear, instead of waiting for the gradual 'coming up' of just swallowing. Once you've snorted the 5-10mg, the other 10 mg you ate should begin to kick in as well shortly after (for some reason, ambien is an EXTREMELY fast-acting drug, it takes effect normally within 30 minutes of swallowing. Just remember to peel off the outer casing of the ambien you intend on snorting, I dont exactly know what its made of, but I'm pretty sure you dont want it going up your nose. Anyway, ambien can be a pretty fun and definitely interesting experience, and unlike acid, once you feel like you've had enough, you can just lay down and fall asleep with absolutely no problems.
