anesthesia
"I'm a cancer survivor and have had multiple surgeries requiring anesthesia.  Typically I wake feeling very groggy and nauseous,racing heart, headache etc. This is the first time I have had propofol. I woke feeling completely alert, was able to stand up immediately, dress myself and walk unaided to the restroom within minutes of waking. I thought this drug was finally the answer, but after several hours I began coughing and sneezing and have not been able to sleep for two nights. I'm on day 3 and my chest feels heavy and I continue to cough. Despite a recent bout w/breast cancer I'm physically fit and strong. I have excellent blood pressure and my resting heart rate is around 50 bpm, which is excellent for my age, not sure why this reaction."
