I take tylenol PM whenever I need to get to sleep quickly and have a full night's rest. Taking them and ignoring sleep is not dangerous at all. In fact, I take these the night before I go snowboarding. I have to wake up early and I get home late from work. Even though I have a different sleep pattern, I can still go to bed quickly and feel rested. When I need to sleep during knee pain or other injuries, Tylenol PM geltabs are simple and reliable. I like gelcaps because they are easy to swallow and digest.
I have had problems some nights with night sweats, though I am not sure that they are related to taking Tylenol PM. Sometimes acetomenophen can cause night sweats, though I am not sure if that is a side effect of Tylenol PM.
