"bubbling, gas, bloating"
Maybe you are lactose intolerant, or eat too much fruit.
My brother has IBS, try staying away from any form of the following:
Coffee, sodas, apple juice, grape juice, beans
When he eats these things, its "all over with".
"Wake up early"
Also try not to eat too late. When I eat late I wake up with insane stomach pains which I have to stop by eating a huge breakfast.
"Sh1tter constipation"
Try drinking more water, that's usually the main reason for constipation.
I am not a doctor, nor claim that my situation can resolve another persons medical condition. This did, and continues to help me when I have the issue as described above. With ANY advice, always make sure to get a second opinion from your doctor or nurse hotline.
I hope this helps!!
