Orange juice?

I am a yr out and can eat most everything.   Woke up early and was doing some chores and got very thirsty.   Poured a cup of OJ, the low calorie kind.   I drank it down.  Almost immediately I vomited.   Too much acid?   Something like this has never happened to me before.  Any comments welcome.

Probably too much acid. OJ is also much thicker than probably most other things you drink and probably doesn't go right through the pyloric valve like water does so it could be that you drank too much too.

oj has a lot of sugar and you probbly are not used to it , lots of sugar came make you vomit or get diarrhea
