Pain
"I had 2 foot surgeries within 9 months of each other that took me over 2 years to heal, and was given Vicodin for the pain. At first it was awesome, it took care of the pain but I slept all the time. After a while I ended up taking more to relieve the pain, which scared me. So I would go off of it for a month or so and live in agony to prove I was not addicted.  It detaches you from whats going on around you. I finally figured out that I would rather be in some pain than be so depressed as that drug made me feel. I just stick to ibuprofen now."
