I have a gram of tested racemic K which I am planning to use this weekend. I have the house to myself so I am going to chill!

I don’t plan to using the full gram but i want to feel good effects too. How should I dose? What should be my first dose and the following doses?

What kind of high/feeling should I expect?

I have done mdma, coke, shrooms, meth, lsd before. I like to smoke nicotine sometimes, especially on drugs. Should i smoke nicotine?

I am not really alcohol person. Do you feel like drinking on K?

I used to smoke weed alot but now i just use it from sleep (very rarely) because it makes me paranoid. Is mixing weed with K a good idea?

I have some mdma too, is mixing a good idea?

Is there a comedown like molly? If yes, do you recommend any supplements?

TIA.
