200ml = how many vodka shots

Note: I don’t know much about alcohol, I just drink and get drunk. Not ever have I done a shot, I’ve always just taken mouthfuls of vodka out the bottle, so I’ve never known how much I actually drink.

(Note: this was done with water) I filled my mouth 3 times to roughly the same amount I’d drink and spate it into a measuring cup(when I drink I take 3 mouthfuls.
I did this a few times and it all roughly sat at 200ml, a little bit over sometimes.

I’ve looked it up but and I get slightly different answers each time, most say it’s 4 shots though but I’m not 100% sure. I don’t even know if 4 shots is considered a lot (I’m 5’7 and 54kg), I don’t drink socially and only at home so I don’t know how the average person drinks. This has been the way I’ve drunk for 4 years, I’m 21 now

(I’ve already cut back a lot, my parter has limited me to only drinking once every 3 weeks. I used to drink till I either vomited or passed out)
