"all this hooplah about the dangers of darvocet.  i used to take tylenol 8 hour, but had to take it more than once or even more than twice a day and it did not take away the horrible muscle spasms i was getting, especially at night.  i take darvocet at bedtime, one time and it gets me through the night and the entire next day.  it works for me and i&#039;m not changing."
