malaria prevention
"I would only take malarone, knowing that the FDA recently put a black box warning on mefloquine, but malarone is really messing me up.  I live in Africa and will be for the next couple of years.  Malarone is causing me to have horrific insomnia, some hallucinations and muscle contractions.  My stomach pain I can deal with along with the back pain.  The insomnia is killing me, though.  I can't work, I walk around like a zombie.  I'm going to take my chances with malaria.  No more pills for me."
