I'm 6 weeks out from my second knee surgery and once again, I am having a terrible time with insomnia. And to make it worse, I get a ton of anxiety and just can't get comfortable. It's almost like a panic attack. To top it off, in week 4, I started experience post-surgery nausea and vomiting. I wake up each more and dry heave and even vomit as soon as I get to the kitchen in the morning. This has lasted 2 weeks. (I did get an anti-nausea medication). Has anyone else had these issues? Some nights I'm still up at 3 am, trying to get comfortable. I have loaded myself up with Zzquil, Benedryl, and other over the counter meds to knock me out. I thought with the opioids I'm still on, it would do the trick. Nope. Am I alone?
