migraine
"I had a migraine for 3 days.  And noticed double vision on day 3.  I had my sister to take me to the ER.  I was given Metoclopramide in my IV.  It worked like a wonder drug.  I have a presciption and haven't had any problems.  3 months later I had another migraine took 10g tablet of regular and took a nap.  Felt great.  Sorry it doesn't work for everyone."
