Any of you have the same issue?

Hey Ya'll so I have done acid about 3 times. Now 2 out of the 3 times I threw up when it came on, the 2nd time was a full tab and I had a great trip but vomited 3 times, the time after was a quarter tab and that made me puke once. I was listening to a terance mckenna lecture the other day and he said if LSD makes you vomit something is wrong and its not a normal occurence, however the first time I did acid I didn't puke at all so im wondering if it was just that specific LSD or what? Any insight will help.
