I already know that I am violently allergic to codeine. Why the nurses never figured out that my vomiting and nausea after my deliveries might possibly be related to the pain medication I received is totally beyond me, but I finally figured out that my body doesn't like it. Then I was prescribed oxycodone after a tonsillectomy and work on my soft palate and a deviated septum. It made me loopy. I knew I was loopy, but I couldn't get my mind under control to stop being loopy. I hated it. Yesterday, I got vicodine. Today, I've felt tired and nauseous, and my brain isn't functioning properly. It's a mess. I pray I am never in a situation where I am in serious pain on a long-term basis.
