"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&#039;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."
