Well reading the other posts seems to have kick started the grey matter a bit. So here goes:
There was a young lady from Rhyl
Who got up to take her pill.
Take it they told 'er
Or before you're much older
The RA will make you quite ill.
She swallowed it down
With a gag and a frown.
She prayed for no bloating
"Cause soon she'd be floating
Around in delicate gown.
