Another thing you could try: Just as you get into bed at night (don't do this too late.. you want to have enough time to sleep so that you can wake up without the aid of your alarm clock), lay back in a comfortable position (in which you can drift off to sleep), and visualise waves of relaxation washing the tension out of your body. Don't worry if you're too tense to notice a substantial difference in your muscles. Notice your breathing.. and become aware of the room around you. Try to let go of any thoughts you might be having (when a thought/worry comes into your mind, see it.. know it.. and, understanding that it is not a bad thing, let it drift away. Plenty of time for it later. Self compassion is powerfully relaxing).
When you feel that you have 'entered this moment'; When you are not paying all that much attention to yesterday or tomorrow (remember.. you have plenty of time for that later. This is your time.. breathe), start the Deep Relaxation tape. Ask your mind (gently.. compassionately) to show you, while you dream (or spontaneously while you're awake) what you can do/change to reduce the internal stresses (conflicts) you are experiencing.
Try this for as long as you feel comfortable. You might be surprised at the power of your mind.. at how much your mind is willing to work with you to make your life more enjoyable.
Take two of these and call me in the morning
