Pain will bring this on, as well as that 24-36 hour bug.
Get a good anti-puke medication, (I use promethazine), along with an anti diarrheal, I use just the otc, laperamide. I had a bout this AM. Had LOTS to do, (much more than my usual) and my nerves just got to me. Fortunately, these took care of it in time.

We've got to have ALL our meds in One Place!
I use a shave kit bag. No razors in there though!

RSD affects our nerves, and when we get 'excited' or worse, 'anticipated', we can really get on the treadmill to NoWhere!

And, you gotta take these meds, BEFORE, there is 'The Symptom', as soon as you feel it coming!
As anything else....

Hope you feel better!
