Effects - Bali kratom causing Nauseau at same dose level as Indo kratom

[REDSOXFAN]

SWIM has taken Super Red Vein Indo kratom for some time now and has never gotten sick from it. SWIM however, just bought a bag of BALI PC and, when taking the same dosage, is getting very naucious and vomitting a few times.

SWIM was able to eat with the Red Vein and, although effects were lessened, SWIM did not get sick.

Now, with BALI PC, SWIM got very nauseated and sick after taking some (about a heaping tablespoon).

Any reason for this? Is Bali that much more potent than Indo? SWIM also tried to take less Bali but got no effects from it. Again, once SWIM ingested a little more, SWIM got sick.

Thanks!
