19 shots at a time?

121 pounds, F, 5’1. im not sure what qualifies as heavy drinker, but on an avg i do 5-6 drinks everyday. I’ve stopped for a month now fearing dependency. but my 19th bday is coming up and my plan was to do 19 shots. had a decent plan on spreading it out over 24 hrs but I can’t do that anymore. any other ideas? maybe i can do beer instead? or do you think its possible to do 19 shots starting midnight? but i have to be sort of sober by noon.
