Severe orange mucus after alcohol

Does anyone else get this with IBS? It's started happening the last few years and it's really horrible! Every time I drink alcohol, which isn't often, once every few weeks, I get gassy and then I feel like my bowel is like internally farting and I know they means there is lots of mucus present. Basically gas and fluid = very loud noises in my bowel that also vibrate. Highly embarrassing! And then I spend the next 6 hours or so having to go to the toilet every half hour or so and passing out copious amounts of gas and bright orange liquid mucus on it own (if I don't pass it, I'll continue to get these super loud bowel noises). That's also embarrassing as I need a toilet where no one can hear me as passing liquid and gas is just so noisy and vile!! I also don't date really because I'm to embarrassed, it sometimes also happens if I can't release the gas in my bowel, I'll start to get mucus. I basically need to be able to fart at all times! But sometimes your in places where you can't go every few mins or your with other people. It's why I like the comfort of my home!! I just want my life back!! Doctors keeping saying ibs but I also have a stubborn yeast infection in my mouth that won't go away even after treatment. Could I have a yeast problem?
