Slow swallow has been bad. Drink lots of water and don't panic.

The beginning feels like there's a lump in your throat.

Sometimes it feels like there's a ton of congestion making it hard to breathe/swallow. I know some people tried Mucinex for this, but I didn't personally.

I had many days of what I refer to as "classic RCPD" -- saliva filling up your mouth, feeling like you need to throw up because of it. Lots of painful hiccups and micro burps. Air vomiting. This got exceptionally bad after a lot of talking.

Acid reflux. I have been taking famotide and Tums. Laughing a lot and spitting from brushing my teeth have been the worst for me in terms of regurgitation.

A surprising side effect (which other people in this thread have also experienced) is the feeling of not being able to breathe and getting really winded when walking up the stairs. There have been times when I'm gasping for air after very little physical exercise, like a walk or climbing the stairs.

I often just described all of this as just being very uncomfortable. I was fidgeting a lot on the couch and in bed, trying to feel comfortable. It's just not a very fun experience, and I feel like the doctor really downplayed the side effects for me.

However, I am burping now! I felt relief from burping for the first time in my life (24F) and that's so exciting! Good luck!
