I’m getting fed up with these symptoms and want treatment but am hesitant

-how common is vomiting after the procedure?
-can you tell the difference between a burp coming up and regurgitation/throwing up?
-how long do the negative side effects (slow swallowing, potential regurgitation, hoarseness) last?
-is there a way to minimize side effects?
I’m a teacher and a dancer so much of my life is active and on the move, with a lot of bending over and standing up. I have SEVERE emetephobia which is honestly the only thing that’s got me hesitant and I know it’ll improve after the procedure but I just can’t seem to get over the hump. But I’m miserable how I am now.
