I live at sea level. Three days ago we flew to Breckenridge, CO (9,500 feet) for a wedding. I took 600mg Ibuprofen three times a day for a few days after reading about a study in which it helped some people prevent Acute Mountain Sickness. I stopped taking so much last night. I had felt fairly good except for just some shortness of breath. Today I have had a mild headache. I have had a few glasses of wine yesterday and the day before (none the day or evening of travel), and a few drinks at the wedding. This evening, I sudden have extremely frequent urination, and some mild nausea and a high level of anxiety. My phone has a pulse oximeter on it, and it is ranging from 87-93. Pulse is pretty normal. Am I just now getting altitude sickness three days into the trip?
