My wife was given a prescription for Darvocet and, as I recall, could take two up to every 4-6 hours. She took only one every 4-6 hours up through Wednesday, the third day, and then switched to regular Tylenol. She stopped even those by the seventh day. She had only minor gas pain and she easily controlled that with Gas-X. Needless to say she has always thought she had a perfect recovery.
