Luckily i've only had it happen twice, but throwing up sucks! Sorry this is TMI, but imagine how small that area is and how hard your body has to push to get that stuff to come back out that hole. It sucks and it hurts. My stomach muscles hurt sooo bad afterwards way more than they usually do when I get sick.
I know most folks keep ani nausea meds with them. I don't, but I think it is a great idea. I'm also very careful when I drink to not drink too much and make myself sick.
HOpe you feel better!!
