I am one that doesn't like to take meds and when I need them, I forget that they are there. I have night sweats even though I had a total hyster at age 31 (now 55). Are you taking both of these at the same time? If so, maybe take them a couple of hrs apart. As for the Tylenol PM, my onco does not want any of her patients on this. She is very cautious about over the counter drugs. I would talk to my onco and see what she/he suggests.
Stay cool...Deb
