Can you imagine the son of God being given a sponge full of vinegar upon a hyssop when he was on the cross and being taunted with the words, "Let us see whether Elijah cometh to take him down." This did happen and is recorded in John 12:28 and is customarily called the fifth word from the Cross. He had just said the words, "My God, my God, why hast thou forsaken me?" He was about to say it is finished and give up the ghost and say, "into thy hands, I commend my spirit." This was very real. Here was genuine relief from his suffering, a drink of pure, sour soldier's wine. By this time, his suffering was most intense. He was undoubtedly tortured with fever, He was thirsty, both because of the natural nervousness of the situation, because of the intense pain, the dust and dryness, his own loss of blood and probably dehydration.
