"i was diagnosed with a missed miscarriage last week, but i had no external symptoms. i waited a week and still no bleeding. so my ob/gyn prescribed for me misoprostol (cytotec) which induces contractions and therefore bleeding etc. i was given tylenol 3 to take to reduce the pain. i had excruciating pain from the contractions to the point that sometimes i could hardly move or talk. i took 400 advil (iboprufen)  and felt a little better. i know the tylenol 3 had no effect on me because it didn&#039;t even make me sleepy, not even a bit.

n.b. i don&#039;t drink, don&#039;t smoke, don&#039;t use drugs and therefore i don&#039;t believe i have tolerance to any narcotics. regular tylenol never works for my kind of pains anyway."
