I had the wired PH monitor three times, and really, while it's not pleasant, it's not a big deal. It's just 24 hours, then you go back and get it pulled out. Sometimes people find the BRAVO test to be uncomfortable as they can feel the capsule pulling. Either one is just a short term discomfort and will provide your doctors with lots of important information!
Don't worry! You'll do just fine either way.
Words of wisdom by Eckhart Tolle:
"Whatever you fight, you strengthen, and what you resist, persists.”
“Worry pretends to be necessary but serves no useful purpose”
“Accept - then act. Whatever the present moment contains, accept it as if you had chosen it. Always work with it, not against it.”
