Can Fasting Help My IBS Symptoms?

Question for anyone who is experienced with fasting: Would fasting benefit my IBS, or would it hurt me? One of my IBS symptoms is getting bloated and gassy at night, so I’ve always tried to stop eating around 5:00 PM or so to make sure I go to bed hungry. That way there’s nothing in my system to make me bloated. I’ve recently realized that even if I stop at 5:00 PM or 5:30 PM, I still sometimes experience discomfort. Would it be hurtful for me to start fasting from 4:00 PM to 7:30 AM, so for a total of 15.5 hours? I read online that most people who fast do it from 14-18 hours, so I wonder if 15 will be good for me? I want to be able to get sleep and not lay there feeling super uncomfortable. I’m able to tolerate hunger pains, but I can’t tolerate bloating pain; it makes me cry like a baby I swear.
