withdrawal advice?

not completely sure if this posts belongs here but i got motivation to stop drinking after seeing my best friend in the hospital suffering from alcohol poisoning. its been a good 2 years or so since i started drinking everyday & im sick of it, im tired of throwing up almost everyday, spending so much money on bottles, etc. but im anxious about quitting since i havent gone more than a couple hours without drinking in so long. i was just wondering if anyone can give me advice on what to expect or if i should even expect anything at all? i know that it’ll be a challenge mentally, but should i be worried about physical symptoms? please & thank you :}

(ps sorry if this comes off as ignorant or tone death in any way, ive just heard a lot of different conflicting things about quitting alcohol)
