Take it right before you are ready to go to bed which means you may need to start getting more deliberate about your sleep schedule. It will absolutely knock you out within about half an hour of taking it. Do NOT try to do anything but put yourself to bed after you take it. Generally, I'd take it, wait the 10 minutes you have to wait before you can eat or drink anything. Then get something to drink and brush my teeth to get the nasty taste out of my mouth before I went to bed. I would start getting drowsy within about 20-25 minutes, head to bed and be out like a light pretty much right away.
