alcohol that’s not very filling or strong?

when i was younger i used to drink anything, 200ml vodka straight in two sips, cheapest cider, never bothered me. now i cant drink anything, usually i drink vodka, water, and diluted juice like miwadi because its light and not very filling, beer and vodka cokes and cocktails fill me up so much then i drink too slow to actually get drunk. but recently even that fills me up too much. taking shots would help with the whole getting too full thing but i get sick at the taste. anyone have any suggestions for a drink that would suit me?
