why isn't my kratom working

i drank 7g on an empty stomach. i used to drink it semi-regularly YEARS ago but now have zero tolerance and literally just got this bag the night before yesterday, it was working fine before this. it has been 1 hour

edit: too tired to reply individually to comments saying the same thing, but i meant i drank it already yesterday and the night before and got desired effects, the batch is most likely fine
