Was googling for an answer to this and found some but wanted to post and ask this myself as most answers focused on immediate feelings of nausea due to quality and I feel this is something different. I'm definitely no stranger to coke binges and it's caused many complications but it's never made me this nauseous, maybe very very slightly due to excitement etc at the beginning but always passes. Been on and off on quite a long binge todays the second time I started to get really nauseous and vomited twice after attempting to drink water, couldn't even wait to get to the toilet.. Its the third day of binge with a 10 hour sleep in the middle but no food and general exhaustion. I wold put it down to this but ive done a lot worse and pushed a lot more and never was sick. Took an anti sickness pill i had from food poisoning and feel totally fine now and even eating some pasta but just wondering what it could be. Had the same source for a while now, could it be cut w something dodgy? But i'm sure I would have noticed the difference. Could I have the begginings of an ulcer or something more serious? Thats my main concern..Need advice!
