A new shade of green

Contest entry, regarding the joy's of throwing up!

Agony grip's my abdomen,
Nearly rendering me dead!

Every pore upon my face,
Enduring horrid shades of red.
Rising in my throat,
Is a rather awful mess,
Even though I know that I have eaten less.

Shall I bloat my cheeks?
Have I ever felt this bad?
Although the feeling comes and goes,
Do I dare believe,
Every twinge that I have had.

Of course I egg it on,
For once it's up I'm done.

Gearing up for it's release,
Ready for the news,
Even I cannot deny,
Even I can read the clues.
NO! I scream out loud, it's landed on my shoes!
