atrial fibrillation
"Started taking Flecainide in 2008.  Doctor suggested 100mg twice a day to control Atrial Fibrillation.  I asked if I could take 1/2 a pill twice a day (50mg x 2).  Even though he said it wouldn't be enough, I wanted to try the lower dose.  My theory was that if I have to take a medicine, the least amount that would serve the purpose would be preferred.  He agreed to let me try the lower dose. The only time I've had atrial fibrillation since is when I forgot to take the medicines.  Four years on Flecainide, so far so good, with no noticeable side effects."
