It is 3:00 A.M. and I still am not asleep. My day started at 6:00 A.M. and I haven't even had a nap yet. I have insomnia again. Some days I can sleep all day, others I can't sleep at all. Needless to say it makes for interesting mood swings. How did I get this way? Dilaudid and Morphine given to me post surgery. I even had my very own dilaudid overdose via PCA, followed by a shot of naloxone. I do not recommend trying this for yourself. The movies that depict people coming around slowly after a shot of naloxone to counteract an opiate overdose lie. What actually happens is that in a split second your body goes from barely breathing and hypotensive to extremely hypertensive, rapid breathing, with your heart racing. The added benefit is that if you just had surgery, you can feel everything. For me that was just no good. After having one vertebrea removed, osteotomy on a second, followed by a 5 level decompression stabilized with rods and screws, you really do NOT want to feel that. So, after a couple more days of a PCA loaded with dilaudid I started to become immune to it. Once I convinced them to take the evil PCA away I was switched to oral morphine. I took it as directed, even less than directed some days, but still suffered withdrawl symptoms. Yuck. This is the lasting side effect, screwed up sleep patterns. Oh well, small price to pay to be pain free and happier.
