Soon to be 21, horrified of vomiting

so I turn 21 on the 28th of this month. I’m excited for it and i have no fear of alcohol or drinking ive done it in the past but one thing i have an absolute deathly fear of is vomiting. I had a particularly bad experience vomitting as a young child and ever since i simply havent done it going on maybe 10 years. when i do drink, i tend to drink only enough to feel comfortable or really put 120% effort into keeping it down. honestly this isnt fun and i never get as drunk as i want and i end up just stressing out, and come my 21st i know my friends will put me through the ringer. Ive been told that vomitting from alcohol is much more ‘pleasant’ and specifically much easier than the normal food vomitting but im still scared to deal with it. i would much rather just be comfortable doing it and moving on with my night. any advice or insight on the matter would be very reassuring
