Hola, mira, las dos son correctas, en mi pais, México, es más común y correcto decir YA NO BEBO o YA NO TOMO. seguido de un GRACIAS. :D

Both are ok. As the conjugated verb "bebo" implies the first person, there's no need to write "yo" but it's not wrong to write it if you wish. Valid alternatives are: ya no bebo no bebo más ya no bebo más yo ya no bebo yo no bebo más yo ya no bebo más PS: remember that as in french, the accents are an important part of the language, so you should learn to write with accents too, as in "más". PS2: I'm learning chinese, so we could exchange some chats to practice spanish and chinese if you wish. bye

I don't drink anymore = Yo no bebo más. Yo no bebo ya.
