How do you function with this pain?

Diagnosed with medication-induced esophagitis, and I am in so much pain. I can barely sleep, eat, or drink anything. I went to the ER and they gave me a ton of meds, but I’m on day 7 of this and feel like I have a long way to go.

When did your pain start to be manageable? How long did your esophagitis take to heal? I was supposed to go on a trip this weekend and I’m worried that I will be home writhing in pain instead.
