My boyfriend and I were sitting on the couch when his stomach gurgled VERY loudly. Then he got up to go to the bathroom. He swears up and down that he didn't have d*, but he's been having a hard time going to the bathroom for the last 2-3 days. I figured it was his diet, so I made him drink some ACV and honey in warm water (supposedly a natural laxative).

We share a 1-bedroom apartment and a small bathroom. I clean the whole thing with bleach every few days, but I'm still terrified that he'll bring something home with him.

His appetite is fine, he has no fever, but the noises and the constipation have me worried. Anyone know what this could be? Anything contagious? And any ideas for natural laxatives other than prunes/prune juice?
