Have you been feeling excessively sleepy during the day? Are you having trouble going to sleep at night, staying asleep, or waking up earlier than you'd like? Do you have difficulty concentrating or staying focused while at work or school? Do you need caffeine to keep you awake and alert? Does the sleep you do get feel unrestorative, or as if it's just not enough?
If your quality of sleep constantly feels like it's just not adequate enough, it's possible that you may have a sleep disorder. And if you feel like you may have a sleep disorder, you're probably going to need to have a sleep study to discover the root cause of your nightly troubles.
Talking with your primary care physician or a sleep specialist about your difficulties with sleep is critical to getting a sleep study performed to find out just what is going wrong. And more than likely your physician will ask you to keep a sleep diary for at least two weeks so he can figure out why you may be having trouble sleeping.
If you want to get ahead of the curve, start keeping a sleep diary as soon as you begin to recognize a problem. It can only help to expedite the process towards proper diagnosis and treatment.
