I Forgot to Eat

I managed to forget to eat today. Since I was up all last night vomiting, I took a long nap today. When I woke up, I realized I missed my dosage of medication. Now, it feels like my stomach has been sucker punched (bad cramps) with an overlay of burning.

I'm trying to eat a baked potato in hopes that it will stay down. I need something on my stomach to vomit because vomiting stomach acid hurts. Also, I'm a bit worried about my teeth. What effect will all of this vomiting have on my teeth?

I wish I could control this pain. The pain goes overlooked by my doctor because the vomiting takes priority. I'm also scared that it's nerve pain and if it is, there's nothing I can really do about it. Nerve pain is hard to treat.
