YOU SAID:
God I wish I hadn't drunk that last night
INTO JAPANESE
神様、私は昨夜、酔っていないといい
BACK INTO ENGLISH
God, I wish I had not been drunk last night
INTO JAPANESE
神様、私は昨夜酔っていなかった
BACK INTO ENGLISH
God, I was not drunk last night
INTO JAPANESE
神様、私は昨晩酔っていませんでした
BACK INTO ENGLISH
God, I was not drunk last night
That didn't even make that much sense in English.
