I have also been feeling more gassy or bloated which has led to me belching more often. Unfortunately, with the nausea also involved, I'm concerned that any given belch could lead to stomach acid going into my throat and mouth. This, in turn, has led to my taking heavily deep breaths as doing so seems to push down and clear the nausea for a little while. Unfortunately, it makes it sound like I'm sighing deeply from despair or exhaustion, which has raised the concern of some of the people who have heard me do it. That concern makes it so that I have become more self-conscious about when and where I am doing those cleansing breaths, which has led to me dealing with more nausea.
The good news is that my body seems to be adjusting to the medicine more so that the nausea is less pronounced and more infrequently present.
