I just took two Nytol 1 a night 50mg sleeping tablets. I have been having real problems sleeping recently hence why I am still awake. Took a tablet and went to brush my teeth and then came back and took another. So I have taken 100mg in total. I am really worried now and don't know what to do, obviously scared to fall asleep. Does anyone know if this will be okay? The active ingredient is diphenhydramine.
