Please help!!

I’ve never made a post on here and not to sure how it works but i seriously need help. i used to take 1 or 2 caps and feel great, no issues at all but 2 years ago i was on it and got sick immediately after swallowing the cap and since then i haven’t been able to take it without throwing my guts up and feeling sick for the next like 5 hours. i’ve tried to google everything and i’ve had no luck. its not like when some other people take it, throw up and feel fine. i’ve tried to tough it out at music festivals and always need to leave because i can’t stop throwing up. i was never a regular user, maybe once or twice every 3 months sometimes way less! i’ve gotten it from the same people i used to get it from and also heaps of different people and it’s always the same result. im in australia if that makes any difference. i’ve got a music festival coming up and i don’t wanna leave early but i also wanna enjoy some m. please please any suggestions or answers. my only theory is i was a bad junkie in my past life and the universe is trying everything in its power to not see me go down that road again😩😩😩
