"i&#039;ve had 3 aortic aneurysms. the last operation also involved a patch placed over a surgical hernia caused from removal of the two lower ribs on my left side.  i&#039;ve been using oxycodone for the past 4 years and aside from insomnia when i take it in the evenings, i am very pleased with the way it controls my pain.  i take it only when i am in pain and limit the dosage to 10 - 20 mgs. (10 mgs per dose, occasionally twice a day).  with this usage, i haven&#039;t had dependency or addiction."
