Alcohol withdrawals

HI all, i am currently going sober for various reasons. i've been an alcoholic for several years now. i am not sure if what i'm going to ask would count as medical advice and i don't mean to offend anyone. i have an exam coming up in 10 days but it is a written exam and my hand currently still shake, i've only been sober for 2 days and it is pretty hard for me to write legible words. how long will it take for the shakes to go realistically? i can't really ween myself off it because i don't even have the money for that. thanks and sorry again if this is offensive or breaching the rules
