"Wine has a strong effect on me."

Translation: Vinho tem um efeito forte sobre mim.

[e.cambourn]

This seems strange. Why is 'em' not used instead of sobre?

[samosborn88]

would sobre de mim be correct?

[Paulenrique]

no."sobre" is already a prepostion, which has no need of an additional preposition.

[Amer.Selimovich]

Is there any other preposition to use here instead of 'sobre' like 'em' or 'para'?

[Paulenrique]

"em" can also be used here.

[Werner912974]

How about comigo

[Paulenrique]

comigo = with me
