Get a planner and schedule everything. Put in there when you have class, when you'll study, when you'll work, when you'll get up, go to bed and spend time with your family. Stick to your schedule, but allow yourself some flexibility for unexpected things that may come up.
Find downtime in everyday tasks that could be put to productive use, and use it. Take your books with you when you go to the doctor's office, and spend the time in the waiting room reviewing your notes or reading your assignment for next week. Take a few minutes to study while waiting for your classes to start. Have your books open on the counter while you're preparing dinner, and read small sections as you cook. Using time that is scheduled for one purpose to take care of two purposes can free up time later on and makes the week much easier to handle.
Many people, especially older students, cannot study for large chunks of time without getting bogged down and wasting time daydreaming. It's a great idea to set small goals and change activities often to stay actively engaged in them. For example, tell yourself that you're going to read 10 pages, then go fold the laundry, then read 10 more. It lets you make the most of your time and get more things done without getting bored with the studying. If you start to feel yourself losing focus, get up and do something for your home or family, then come back to your studies. Even a five-minute break to close your eyes, imagine a sunny beach and relax can do wonders for putting you back on track.
