29F alcoholic, can I reasonably quit drinking with no assistance?

I'm 29 and I've been drinking since I was 19 or 20. For the past 2 years I've been drinking about a fifth of tequila every day, give or take. I've heard about people having seizures and stuff when they quit but it seems like they tend to be older people who have been drinking for like 20 years. Would it be safe for me to just stop without meds or anything? I don't have insurance or anything so I'm trying to avoid that. I had my liver checked like 8 months ago and they said it's normal.
