Everytime I take Tylenol extra strength, I get extremely tired and I go to sleep for about 4-5 hours. This happens every time I take two pills, but only for the past couple years. I used to not get tired from Tylenol like this. I also always start to sweat and feel feverish although my temperature doesn’t go past 99 degrees. It’s a very strong feeling. When I take it while I’m outside i feel like I’m about to pass out from exhaustion. I take it for period cramps and headaches. Nothing else works
