Hello, I was taking pain medicine, XTAMPZA and I was taking 1 capsule everyday. I could not understand why I still had pain. I realized last week why I had so many pills because I am suppose to take 1 every 12 hrs. not just one a day for 24 hrs So last week I started taking 2 and pain was at bay, not much at all,great. Well yesterday and today around same time, 3:30PM 4:00PM dizzy, nausa, possible vomiting feeling. Is this due to the medicine?
