Migraine Prevention
"The drug would get a 10 as it worked miraculously for me.   In my case -- and this probably won&#039;t happen to you -- the medication caused me kidney stones, the first of which was agonizing and led me to stop using the medication.  Then the headaches resumed.  I was willing to take an occasional Kidney Stone attack as a tradeoff for frequent migraine so I went back on the drug knowing the risks.  Unfortunately, I peed gravel constantly, oddly without pain, but it was a warning.  I&#039;m now off the drug.  If it did not cause me that side effect, I would have remained on the medication as it was, again, close to 100 percent effective.  Not everyone responds the same way; your experience will probably be different."
