I personally recommend starting really low like 1-2 grams then seeing how that effects you as in my experience less is definitely more for stimulation and mood lift is still present.
It doesn’t seem to impact my psilocybin experience in a negative way. I just mixed the two last week and had a great experience.
Just some background on my experience with kratom. I started on large doses because I was on opioids for years. Last time, I was on suboxone maintenance at 16 mg a day for 5 years. I quit suboxone about a year ago, but I tend to be an extremist when it comes to drugs so I started at about 10 grams a dose which I increased to 20 grams a dose three times a day. I started decreasing my dose because I am one of the small portion of the population that gets some side effects from it like tinnitus and pain in my liver for example.
Well, I got down to 3 grams per dose three times a day and I still get nearly the same stimulation and mood lift as I did nearly as I did at a high dose. I highly recommend starting low especially with your opioid history being very light.
Kratom is more potent than codiene if I recall correctly.
The only exception to this is if you are taking it for pain, but you’re not so I would definitely take it low first. I can’t recommend this enough.
I just recalled that this post was a bit ago. Did you try it yet? At small doses in the majority of the population I believe kratom is safe.
