I have a bit of experience with Ketamine, which is extremely sedating, but I have more experience with more stimulating dissociatives such as MXE. They are quite different than psyches like LSD, mushrooms, or phenethylamines.
In general, small doses feel euphoric, and it can be a bit like alcohol/opiates in its intoxication. High doses bring about a trip that can be IMO just as profound as traditional psyches. Moderation is always the key dude. Used properly it can feel very clean, blissful, and liberating. Abuse dissociatives and they certainly can take you to a dark, dirty, lonely place (but so can psychedelics). Start low dosage and work your way up.
I personally love MXE/Ketamine because you dont need to plan a 6-12 hour saga in order to have a solid trip. But beware, the rabbit hole can be extremely addictive, and if you chase it too fervently, it can bite your ass like you can't imagine.
Effects are subjective, and no one can really describe a dissociative trip/hole to you. Gotta try it yourself. I won't promise you will enjoy it as every one has different tastes. But I will say it can be rewarding and highly therapeutic. If you're ready to make peace with mortality/life I'd say take the trip. Personally dissociatives have helped my anxiety/depression more so than psychedelics. LSD makes me a neurotic mess, whereas K relaxes me and gives me peace of mind.
Abuse of dissociatives can eventually cause the same paranoid neurosis I get with LSD. Start with a small dose and try for yourself.
Also long term effects, dissociatives tend to be a little rougher on the body , and abuse of K has been proven to cause bladder problems.
PS. Start with small bumps. 200 mg is a massive dose of K. If you have a scale, weigh out 10-20 mg and sniff that. Wait an hour to see how you feel, and proceed with those small bumps until you learn the substance. Cant stress enough that unlike LSD, you can use Ketamine daily and it can hurt your mind and body with addictive abuse.
