Side effects - Kratom nausea the day after?

[Paroxysm]

Swim took some kratom last night for probly his 3rd or 4th time (he only really got good effects once or twice). He took about 25g of kratom between 9:30 and 11pm ( I know it's alot but for some reason 5-10g isn't enough... barely even noticeable for swim). swim was fine all night, he went to bed at around 2am. The effects weren't too strong and he has definitely felt stronger effects off even a less amount of kratom before which was odd because there is no chance he's built a tolerance for it yet. It should also be noted swim's stomach was empty or close to it. Anyways, Swim woke up at 5:30am and all the sudden felt very nauseas, he ran to the washroom and puked up about 1/3-1/2 of the kratom. He went back to bed woke up at 6:30am and puked again. Swims alarm was set for 7:10am and he got up, had a shower, and puked some more after the shower. He felt kind of better and decided to half some breakfast and a coffee before going to work. As soon as he got to work around 8:15 he brought up alllll he had for breakfast and the coffee. The alphabets cereal tasted just as good coming up as they did going down. mmm. anyways, about an hour after that he had to puke again but was just dry vomitting which is even worse oO.

This has never happened to swim in his other experiences and turned him off kratom for good. One of the roughest morning ever lol. He knows it was a lot of kratom but he needs to take that much to get good effects so it's clearly not even worth it anymore. Anyone want some free kratom? lewl jk. Just wondering if any other peeps vomit the morning after?
