looking for advice (again)

so, i live in a country with free healthcare.

i'm on my summer break from school rn and dealing with symptoms for 4-5 months.

early on i tried Pylera but quit because of the intense side effects, not being prepared or knowing beforehand.

now i have an endoscopy and resistance testing appointment for the 17th august, and a package of Zac Pac (triple therapy with amoxi & claryithromizin) at home.

So the beginning of another antibiotic treatment would be in around 2 months since the wait for every single appointment at gi takes 1 month +

Now I'm contemplating starting Zac Pac today to finally get it over with, or waiting it out but undergoing it during my last year of school, which scares me because i don't want/ can't miss many hours.

Now during holidays i only work once a week.

Any opinions?
