Morphine
"15mg 3x a day ER. I've been trying to find the right medication to treat fibromyalgia pain. I've experienced nearly every side effect, worst being respiratory problems and weight gain. My attitude has been poor and I'm completely miserable. It's increased my depression. For all the horrible side effects I've experienced, it doesn't seem worth it to stay on the medication for MINOR pain relief. The same has happened to me with Lyrica (neurontin with a prettier name) and tramadol ER. Morphine is by far the worst. I gave it 2 weeks but I can't take anymore of the nausea and illness this medication has caused. I took a morning dose today and feel ill, as usual. I can't wait to flush this garbage from my system."
