Codeine
"Had 4 wisdom teeth taken out this morning at 8:30am. My dentist prescribed some codeine for the pain. Having never taken codeine before, and the label reading take 1 or 2 pills for pain, I decided to take 2 around 12:30pm. WOW, these things take all of the pain away alright, however, for about 1 - 2 hours they made me very drowsy, out of it and I couldn't look at anything with a screen without it being blurry or me feeling dizzy. I was literally glued to my seat. Thought I was going to throw up at one point too.  Should probably only be used for chronic, unbearable pain - otherwise it is not worth the side effects. Still feeling a little woozy now at 10:00pm. Will stick to the softer stuff because it seems like I am really sensitive to it."
