Tried K for the first time

This was after a rave when we got back after doing 350mg mdma (I know a bit too much), decent amount of 2cb, and two bumps of coke.

My friend offered us some K, me and my girlfriend were like why not. Did a small key to start, then another one 20 mins after. Things started to feel funny in a good way.

Then my friend said, do 100mg, split it into two, did the first half. Things got wonky in a very good way. Did the other half maybe 30 mins after, things got even wonkier. We followed it up with about 3 more bumps spaced 10-15 mins apart and went to sleep straight after. I was so comfortable in bed, so calm and just knocked me straight out. Overall very funny, weird experience.

Our checkout was 11am, slept at 9am. I honestly felt so refreshed considering I had less than 2 hours sleep, went to an 8 hour rave and did mdma.

My questions are;

Do you always get this sort of afterglow after doing k?

How much of a break should you leave between sessions? I know you build a tolerance to it, unlike 2cb which is my go to.
