I agree with Scott. That's how my blockage started! I kept taking Phazyne or Gas-x for gas relief and nothing worked! I was nauseated and threw up, then felt faint. In 2 hours I was on the floor in a fetal position and my husband was calling the Squad . What does the water intake do? I would have thrown up anything including water that I'd drink in a blockage. I know in the hospital i was NPO, only IV. I had no oral water or even ice chips until the blockage was opened 4 days later.
