I use kratom 7-8 times a month. My usual dose is 4-5g sometimes 6. Always in pill form. Used the powder yesterday for the first time and realized after I consumed it I took about 11g. About 2x my highest dose I've ever consumed.
Felt some nausea, smoked a bit, then nothing. No buzz, no pain relief, didn't really feel anything buy the nausea.
Now today I measure out 3.5g accurately and no nausea, mild euphoria, and pain relief. I feel good. After yesterday's dose I just felt blah, no anything.
So that won't happen again but is it tolerance build up that allows people to take 10mg doses 3x a day and get relief?
